New toughness choices

NEW CHOICES OF DI TENACITY

High temperatures and pressures, intense and prolonged mechanical stresses, reduced spaces in the compartment under the bonnet of the cars constitute a demanding test bench for the components in use that are placed there. In competition with the large production volumes and the high quality standards required, the stressful working conditions require dedicated materials an excellent performance profile, which can be spent in many equally heavy-duty sectors. Even the metal replacement strategies and the engineering trend that thins the thickness into components with complex geometries fuel the demand for ultra-tough plastics.

The most widespread is polyamide 66, flanked by a growing variety of polymeric bases with excellent performance in all items.

COMPETITION GRADES

The problems of the industries that are dedicated to the production of technical components set the agenda for a specialist in high-performance technopolymers such as DAIRE Chemicals, which presents the Italian market with new grades developed by the major brands for high demanding applications. The PA66 reinforced with Leona 14G glass fibers by Asahi Kasei is characterized by prolonged resistance to fatigue and thermal aging: the formulations of this range are widely used in automotive applications such as covers for cylinder heads, torsion bars, engine supports, housings for compass sensors. For the molding of components with walls of reduced thickness, a high fluidity grade has been developed that allows the filling of complex figures without sacrificing the resistance to thermal aging. The Leona 14G range by Asahi Kasei is currently available in versions with glass fiber charge present from 15 to 50%, black in color, heat stabilized and in contact with glycols. Workability in competitive cycle times is the primary target even in a another new product of the brand: the suffix HC of the Tenac C-HC copolymer acetal resin, nomen omen, identifies the marked crystallinity (high crystallinity) of a formulation that is positioned between the copolymer and homopolymer acetal plastic materials, designed to provide filling speed higher than the standard keeping the mechanical properties unchanged. On this side the material behaves very well, like the homopolymer acetal resins, which equates for resistance to fatigue, impact, aging, chemical agents and for E / kg savings. Compared with the copolymer acetal resins, the products of the Tenac C-HC series take advantage of rapid cycle times, particularly thin thicknesses and reduced weight, superior thermal and mechanical resistance.

COMPETITORS WITH STRONG CHANTS

Quality and variety of the offer are essential for an attentive distributor who is constantly in tune with the needs of processors and manufacturers like Daire Chemicals.
In parallel with the improvement of the already excellent technical performance of nylon 66, alternative proposals have multiplied, stimulated by the availability not always adequate to the demand and by the increase in prices that for some time have questioned the choice of polyamides.

Polymer developers have developed effective polypropylene based formulations with fiberglass reinforcements. The proposed grades included in Daire's portfolio are materials resistant to aggressive chemicals, impacts, continuous temperatures up to 120 ° C and peaks at 150 ° C. Thanks to the low propensity to absorb shocks and humidity, they maintain dimensional stability over time. They are competitive with the PA 66 in terms of weight and price, lower than Daire, even 30%; other saving factors can be identified in the possibility of eliminating the drying phase before molding and in workability at lower temperatures compared to the loaded polyamides. Completing the excellent technical data sheet of these PP formulations reinforced with fiberglass is the low noise and vibration generation.

PBT IN GREAT SHAPE AND VARIETY

The Chang Chan Plastics Group (CCP), founded in 1949, is in second place among Taiwan's petrochemical companies in terms of production volumes and is reputed to be one of the largest chemical suppliers worldwide, the first in the world for PBT production. The high profile of the polymers of this brand convinced Daire to conquer its distribution on the Italian market. CCP has developed a very wide range of PBT formulations. The material is widespread for heavy-duty use with excellent mechanical, thermal and electrical characteristics, chemical resistance, dimensional stability and low water absorption; it too is therefore a valid competitor of the PA 66. The 1000 series is articulated in non-loaded degrees, the 2000 series in non-loaded degrees with self-extinguishing properties. The 3000, 4000 and 5000 series identify PBT-based compounds loaded with glass fiber; in particular, the 4000 series has self-extinguishing properties in the V-0 @ 0.8 mm class and the 5000 series, equally dedicated to applications requiring fire protection, is self-extinguishing and halogen-free. The 6000 and 7000 series are developed to provide prints in which deformation phenomena are reduced to a minimum.

High performance technopolymers to effectively support the serious challenges faced by the medical sector.

TO OVERCOME THE EMERGENCY

Faced with a pandemic, that is, an epidemic that affects everyone, everyone must do their part. Many companies have converted their production into medical items or have increased the production capacity of various products that are used to deal with the current emergency health situation. The diversified range of materials distributed by Daire Chemicals, through the suppliers Arkema, RTP, Samyang and Trinseo, is able to support the manufacturers of different devices, with specific solutions that meet the different application needs.

BARRIER EFFECT

Arkema products include Kynar PVDF, Rilsan Clear transparent polyamide and Pebax polyamide and polyether block (TPA) thermoplastic elastomer. PVDF Kynar is usually used in water treatment components such as pumps, membranes, filters, fittings, given its purity and high chemical resistance. In addition, it has an effective resistance to various sterilization systems, such as autoclaves, chemical treatments or radiation. Arkema has also developed special grades of Kynar for the production, through Meltblown and Electro-spinning, of the yarn / fabric used in the masks. The Kynar guarantees a greater germ barrier effect, longer life and allows you to breathe better than the classic non-woven fabrics in PP, TPU or PP / TPU. Many companies are converting their production of eyeglasses or sunglasses, into safety glasses, within the sphere of individual protective devices called PPE. For these productions Daire can supply Rilsan Clear G850R transparent biopolymer, from renewable sources, which is already used in the eyewear sector, in particular for frames, and which, compared to traditional materials such as PMMA and PC used for PPE, it guarantees greater transparency, lightness, impact resistance (especially at low temperatures), chemical resistance to detergents, resilience especially in those parts near the bar subject to opening / closing of the glasses. To ensure better comfort for the wearer, Pebax can be used, which with hardnesses starting from 25 shore D gives a soft-touch effect, useful, for example, in the temples of the glasses.

MEDICAL INSTRUMENTATION

The American company RTP Company has a Healthcare division, 100% dedicated to the sector, and offers solutions suitable for different areas. The polyester based polymer alloy RTP 2000 HC has a high chemical resistance to disinfectant agents used for medical equipment in hospitals and for all those laboratory instruments that are used in these areas. Usually, PC / ABS, PC / PBT, ABS, PC, PC / ASA based materials are used to produce these components and in the long run the chemical aggression of disinfectants mechanically weakens these products, making them unusable. In this case, the RTP 2000HC series comes to the rescue, which extends the life cycle of the equipment, maintaining the same dimensional stability as the polymers normally used. Furthermore, it can be easily colored and also available with self-extinguishing grades UL 94 V-0 / 5VA. To protect medical instruments and laboratory equipment from electrostatic charges and electromagnetic interference that could compromise the results of the analyzes and their correct functioning, RTP produces permanent and conductive antistatic polymers, capable of fully overcoming this problem. For the creation of surgical instruments and equipment, which must withstand countless sterilization cycles according to the various techniques (gamma rays, autoclave, etc.) without difficulty, RTP offers structural compounds, reinforced with fiberglass, glass balls, long fiberglass. , on different bases: PPSU, PPS, PEI PEEK. Also from RTP are masters that make radio-opaque surgical room instruments, therefore visible during surgical interventions, in particular to meet the needs of minimally invasive surgery and of video-assisted and guided surgery. These masters are compatible with polymers such as PPSU, PEEK and autoclavable.

A PROTECTED VISION

As for the manufacture of the glasses used in the field of personal protective equipment, Samyang produces Trirex polycarbonate, which stands out for its excellent optical quality. If you want to equip your protective glasses with softer and more comfortable nose pads and temples to wear, the thermoplastic rubbers based on TPE - Megol and TPU Apilon 52, both from Trinseo, come in handy. In addition to providing an effective soft-touch effect, these materials have a firm adhesion to polycarbonate, therefore they are ideally suited to coating the points of contact with the nose or the parts of the rods resting on the ears. For 38 years Daire Chemicals has specialized in high performance technopolymers. In addition to providing a wide and diverse range of solutions, the company provides the customer with the necessary support to identify the most suitable material for its needs and to transform it into quality products. In the current health emergency situation, it is ready to make available its expertise and the know-how gained alongside companies in the most varied application sectors, to face this challenge and overcome it, together, with positive results.

 

Daire introduces Leona to Italy

The Italian distributor will follow the sales of the partially aromatic PA 66 of Asahi Kasei.

Daire Chemicals has obtained from Asahi Kasei the distribution in Italy of the partially aromatic polyamide 66 Leona 90G, which is added to the other technopolymers of the Japanese group already marketed in our country, in particular Tenac acetal and PPE Xiron.

The Leona series, characterized by competitive costs compared to other aromatic polyamides, is indicated where the metal needs to be replaced, or combined with it, also thanks to a very similar thermal elongation. Grades with different fiberglass content, up to a maximum of 60%, mixed glass / mineral grades and special types approved for contact with drinking water are available.

The Italian distributor also reports another characteristic of the material, the mold temperature of only 90 ° C, which improves its workability, reduces energy costs, allowing water rather than oil cooling, without compromising the mechanical properties or the aesthetic quality of the final product.


Compound hi-tech for individual protection devices

In recent months the demand for personal protective equipment (PPE) has grown exponentially, in particular for masks, visors and glasses. To support the demand for the raw materials necessary to make them, Daire Chemicals (Pianezza, Turin) was also activated through the support of historical partners. In collaboration with Arkema, for example, it offers special grades of PVDF Kynar® for the production, through meltblown and electrospinning, of the fabric for disposable surgical and reusable masks. The material guarantees a greater germ and droplet barrier effect, but also superior durability and breathability compared to the classic non-woven fabrics in PP / TPU and TPU. The product profile is completed by the certification for medical use issued by various international bodies. The high chemical resistance and to the various sterilization technologies (in an autoclave, chemical or radiation) makes the PVDF Kynar family the ideal candidate also in the production of components for water treatment, such as pumps, membranes, filters and fittings. For the realization of glasses and visors, Arkema offers Rilsan® Clear G850R, a transparent polymer obtained from renewable sources. Already particularly appreciated in the eyewear sector, especially for the frames, the material, compared to the plastics commonly used for PPE, such as PMMA and PC, guarantees greater transparency, lightness, impact resistance especially at low temperatures, chemical resistance to cleanliness and great resilience especially in the parts near the bar, the most subject to the stresses due to the opening and closing of the glasses. To ensure better comfort in the use of glasses, you can choose Pebax®, Polyether Block Amides, which with hardness starting from 25 shore D allows to obtain a pleasant soft touch effect, for example on the temples. The range dedicated to frames for glasses includes the Pebax Rnew 70R53 obtained from renewable sources and the transparent Pebax Clear 1200. Both grades are also available for soft touch applications on Rilsan Clear G850R.

The performance of new sporting goods and small appliances has a common denominator: technopolymers specialized to provide added value to the product.

IN THE HOUSE AND OUTDOORS

Throughout its history, Daire Chemicals has developed several applications for the sports and home appliances sectors. Although these are very different sectors, both have demanding and specialized requests, which must be met with raw materials capable of responding effectively and specifically efficiently. With the aim of providing the customer with the most suitable material for his needs, Daire Chemicals offers a wide range of materials, supporting their choice with their expertise and the experience gained in 36 years of activity.

SAMPLES IN ALL FIELDS

"One of the first important applications developed for the sports world has been in the underwater sector, - remembers Stefano Urbinati, product development manager at Daire Chemicals - where we specifically formulated a recipe for a thermoplastic elastomer able to chemically adhere to polypropylene. This allowed the adhesion of the blade of a fin on the shoe, replacing the vulcanized tires previously used. It was the early 90s and thanks to our recipe, we came into contact with API (today Trinseo), with which we followed the underwater market, located mainly in the area around Genoa. Today, unfortunately, that world has very delocalized production, but has remained in our DNA accumulated experience in this area that we have been able to transfer to other sectors. Currently, we have an interesting range of products in distribution that allows us to effectively follow the sporting goods market. The main products used are the soft materials of Trinseo, with tires on TPE-S Megol, TPU Apilon 52 used for example for grips of ski poles, fins, masks and diving equipment, rods and nose pads for sports glasses, soles for sport shoes. As for the tires, we can then increase the properties of resistance to cold, lightness and mechanical properties with the Tema - Pebax by Arkema. It is a product used in the soles of sports shoes but is also used in the padding of bicycle saddles. Arkema also produces transparent amorphous polyamides under the Rilsan Clear brand, used in the production of frames and lenses for sports glasses and ski goggles. This regards what requires softness, lightness and impact resistance. The new demands in the sports field, however, also concern rigid, super-performing and lightweight materials for the metal replacement of structural parts in components for bikes, skis, and snowboards. We are therefore able to meet these requirements with the carbon-fiber-reinforced compounds, long and lubricated glass fibers of RTP Company. We are talking, for example, about ski bindings, parts of bicycle frames, brake levers and much more. Then we have the polycarbonate and PC ABS products of Samyang for the production of ski helmets, snowboards, paragliders, etc., with impact resistance performance superior to the classic ABS helmets. It should not be forgotten, then, that the sports world also means "fashion": to those who require special effects, such as metallic, fluorescent, glow in the dark colors, we are able to respond with the 'special effect' compounds of the RTP ".

APPLIANCES INSIDE AND OUTSIDE

"Applications for the small household appliances sector - continues Urbinati - may require very different raw materials depending on whether they are intended for external or internal components. The bodywork of a coffee machine, for example, must be beautiful, made with aesthetic materials, with colors that attract the customer. Therefore we suggest the use of alloys based on ABS, PC-ABS, or with metal or chrome effect. If there are transparent parts in the kitchen appliance, designed to show the level of the water or the contained food, you are faced with two requirements: firstly, the plastic must be suitable for contact with food and, in certain applications must also be free of bisphenols. In this case, we use Arkema's Rilsan Clear products approved for contact with food and without bisegolo. On the other hand, as regards the interior of the appliance, plastic is called upon to meet various challenges. The main concerns the mechanical properties of stiffness and resilience, thermal performance with peak temperatures that can reach even 100 ° C, chemical properties for contact with food (such as coffee that is very aggressive), organoleptic, not to affect negatively on the taste of the food, therefore it is necessary to choose materials as "pure" as possible.

High performance technopolymers, specialized to solve specific application problems and to evolve products to a higher quality level.

IN THE GUIDE OF INNOVATION

Always a forerunner of new applications, the automotive sector has contributed, with the development of solutions capable of responding to their needs, to stimulate the search for new materials with higher performance, which can then be used by other sectors. In particular, the tendency to lighten vehicles to reduce CO2 emissions and fuel consumption has focused car manufacturers to rethink the various components to make them plastic, lighter than metal, without compromising on quality and performance. performance. With the aim of providing the customer with the polymer best suited to its specific needs, DAIRE Chemicals is particularly attentive to the evolution of market demands and offers a wide range of materials, supporting their choice with their technical expertise. "As part of a generalized search for lightening, - explains Stefano Urbinati, Head of Product Development at Daire Chemicals - the automotive sector has highlighted specific needs in recent years. These include an increasing demand for materials capable of providing high aesthetic results, of polymers that reduce the noise between components, of materials characterized by greater resistance to aging, atmospheric agents and UV rays. In the field of under-the-hood applications or for critical environments, the need for technopolymers capable of withstanding even higher temperatures increases. Often, then, these needs are combined: for example, a piece must provide structural strength, dimensional stability and aesthetic finish.

MARKET

For each application objective we propose the most suitable polymers to provide the most advantageous mix between performance, productivity and costs ".

THE 'BEAUTIFUL' OF SAVINGS

"The aesthetic aspect - Urbinati continues - is one of the key factors for the automotive sector. To reduce the costs related to finishing operations, eliminate the painting phase from the production process and avoid the emission of substances harmful to the environment, the materials that give the injection-molded parts a metallic effect are increasingly sought. We offer polymers based on polycarbonate, ABS or PC / ABS, used to make ring nuts, frames, parts for the dashboard or for the flying area, but also to produce external components ".

"As for the components in the dashboard of the car or heavy vehicles, RTP has developed very special materials, able to reduce the so-called 'squeak', or those annoying noises caused by the friction between the various parts in plastic and not . These polymers - Urbinati points out - are ready to use for injection molding and are filled with fillers that prevent the emission of these creaks. Moreover, they are materials endowed with an effective mechanical resistance, of dimensional stability and, since they are usually based on ABS, they also provide notable aesthetic results: an aspect that is anything but secondary when it comes to components for car interiors ".

THE MOST 'WARM'

"The engines of the latest car models are increasingly compact and powerful. This - underlines Urbinati - means for producers the need to find materials able to withstand ever higher temperatures, obviously without neglecting the need to contain the weight of the components. In response to these requests we offer a series of high performance technopolymers. The resins of DIC, based on PPS, are able to withstand temperatures over 200 ° C in continuous, are characterized by intrinsic self-extinguishing, an efficient dimensional stability, very high mechanical characteristics and a chemical resistance to a wide spectrum of substances . Gharda's G-PAEK (PEK), with a glass transition temperature of 152 ° C, a melt temperature of 352 ° C and a continuous use temperature of 280 ° C, provide higher temperature performance than PEEK , maintaining and often improving the physical, mechanical and chemical resistance characteristics. Among the products we distribute, we also find materials such as the lubricated compounds of RTP which combine thermal resistance with resistance to wear and friction. These materials can be used to make gears, levers, components subject to rubbing, even for areas near the engine or where the temperature becomes higher ".

ANTIETY RECIPES

"When it is necessary to provide the pieces with greater ability to withstand atmospheric agents, UV rays without yellowing or showing signs of aging, specific formulations can be used. RTP has developed a series of poles

propylenes reinforced with long glass fibers or additivated with UV stabilizers that can be used as an alternative to polyamides. In addition to ensuring effective performance in terms of resistance to aging, these materials also provide a specific weight reduction. In fact, compared to the PA, their specific weight is about 10% lower, and they also have a slightly lower cost.

These classes of PP loaded with long glass fibers - concludes Stefano Urbinati - have been approved as resistant to aging according to American standards, being RTP a US company, but they are already in phase of harmonization with Italian and European regulations ".

HIGH SPECIALIZATION PP

Within its range of compounds, RTP has developed some PPs capable of efficiently replacing other more expensive materials. The very long fiber polypropylene compounds (VLFPP) have an advantageous performance / price ratio and a lower specific weight, thus providing an interesting alternative to loaded compounds such as glass fiber reinforced nylon 6 and 6/6. In addition, the PP retains its characteristics unaltered even in the presence of a high moisture content (50%) and its low permeability provides a chemical resistance higher than that of PA. Last but not least, VLFPP can be processed at lower temperatures and pressures than glass-filled nylon, do not require drying and have shorter cycle times: which translates into energy savings and production costs. Another class of PP concerns the development of mass colored solutions. RTP has developed a series of UV stabilized PPs capable of achieving 100% color matching.

Dedicated to applications for car interiors, such as headrest consoles, console and central area, interior handles and step plates, they have reduced deformation, low gloss (2-3), resistance to scratches, mechanical strength and combine structural properties and chromatic harmony . For exteriors, RTP offers a range of black VLFPP usable for components that require a slightly rough finish combined with structure, aesthetics and UV resistance. These materials with low deformation eliminate the need to paint the pieces and have a lower weight than the polyamides loaded with glass fiber. They can be used to make luggage racks, mirror housings, footpegs and exterior handles.
