Thermocomp HMD-D is composed of six grades of glass fiber reinforced PC, which is said to provide a unique combination of stiffness and ductility, making parts lighter, thinner, and stronger. Metal replacement applications range from smartphone housings to medical device housings and internal panels for public transportation.

Ascend Performance Materials discusses new nylon 66 copolymers for films used in food (such as meat and bones) and industrial packaging (such as aircraft parts). They are said to have higher transparency and better puncture resistance than nylon 6 and 66 sex. They are also being explored as the inner layer of 3-5 layers of HDPE resin pellet bags to increase strength and thereby allow thinning.

LANXESS also focused on the new nylon and added several other nylons that we previously reported. A key focus is the new thermal stabilization system XTS2 (Xtreme Temperature Stabilization) for nylon 66. According to reports, the system can withstand long-term temperatures of up to 446 F (230 C), providing an alternative to more expensive high temperatures. -Heating special thermoplastics, such as fully aromatic or semi-aromatic nylon or PPS.

The first grade of the STS2 series is Durethan AKV35XTS2 with 35% glass. Compared with nylon 66 with standard copper-based stabilizers, its long-term thermal aging performance is much better. The new nylon has enhanced fluidity and can improve the surface quality and filling of complex geometries and thin walls. It is designed for automotive engine applications exposed to abnormally high temperatures, such as intake manifolds with integrated charge air coolers or air pipes located near the turbocharger.

Radici Group has also developed a grade of automotive glass fiber reinforced nylon 66 that can withstand temperatures up to 410 F (210 C). To meet the growing demand for electric vehicles, Radici has developed a flame-retardant blend of nylon 6 and 66 for charging sockets, battery housings and battery covers.

SABIC's new thermoplastics also target new mobility options. Including a new type of high heat, high energy density dielectric material, Ultem UTF120 PEI film, the thickness is 5-10 microns. It is used to produce lightweight auxiliary capacitors that help offset the weight of electric vehicle battery packs. Another example is the new Noryl NHP5054, which is a reinforced flame-retardant glass-filled PPE that reaches UL 94V-0 at 0.75 mm and is suitable for structural components such as battery pack housing components.

SABIC also demonstrated a major breakthrough in using its Extem thermoplastic polyimide (TPI) to produce infrared optical sensor lenses for proximity sensing and gesture recognition in smartphones, video game controllers, and drones. It has high thermal dimensional stability with a Tg of 512 F (267 C). Other similar resins cannot be melt processed or injection molded. It is said that, compared with the grinding and polishing of quartz glass and the curing of epoxy resin, Extem's mass micro-molding has many advantages-fast speed, consistent quality, and avoiding costly secondary operations. SABIC showed lenses made of Extem TPI and nylon 12 overmolded.

Nylon Corporation of America (NYCOA) demonstrated a series of nylon-based TPEs, also known as polyether block amides (PEBA). The specific gravity of Ny-Flex elastomer series is lower than TPU. It is suitable for automobiles, sporting goods, personal electronic products, composite materials and special films. Its hardness ranges from 82 Shore D to 90 A. They are said to exhibit excellent flexibility at low temperatures, excellent performance retention at high temperatures, and excellent toughness and elasticity. It also claims to have high creep resistance, strong bending fatigue resistance, good abrasion resistance, and excellent resistance to grease, oil and solvents.

Lubrizol demonstrated Estane TPU and Pearlthane Eco TPU for 3D printing and other new products, which have up to 46% bio-based content, lower density and higher low temperature flexibility, which can be used for highly flexible films or touch Soft injection molded parts. Also new are Estane VSN self-healing TPU, which has the unique ability to repair minor scratches in consumer products such as high-end glasses; and Estane ALR TPU, used for paint protection and graphic packaging of commercial trucks. Compatible with adhesives and topcoats, it is invisible, self-healing, impact resistance and weather resistance.

NatureWorks collaborated with Electrolux and another OEM to showcase the newly developed PLA-based refrigerator lining to compete with the existing HIPS structure. Now in field testing, one method is to co-extrude a sheet with an acrylic core and Ingeo PLA outer layer, and then thermoform it. Both layers are impact-modified. The other key performance characteristics of the new liner are very similar to HIPS, and can also replace ABS liners; they run on existing equipment that has undergone some process modifications. The tolerance of Ingeo to edible oil is equivalent to that of ABS. The cost is expected to be competitive, but due to Ingeo's higher stiffness, there is an opportunity to further reduce the thickness.

Another method being explored requires fully extruded amorphous Ingeo PLA, which becomes semi-crystalline during thermoforming. Both methods are applying for patents. The new entrant Total Corbion PLA has introduced a new technology that can create a completely three-dimensional composite PLA-a material with long, regular interlocking polymer chains, which is used in a wide range of industrial applications, automotive hood components, aerospace , Ships and electrical appliances. According to reports, this proprietary technology enables PLA applications to withstand temperatures close to 392 F (200 C). The company is providing glass-reinforced three-dimensional composite PLA samples for testing.

A. Schulman launched Eco-Flex RTPV, a recycled TPV compound that also contains BASF’s Ecoflex biodegradable aliphatic copolyester.
