HIGH TEMPERATURE PLASTICS | MATERIALS


The combination of lightweight construction and rigidity makes it optimal for high-performance sports equipment, says Xenia. The material raises product durability without adding unnecessary weight.


In the industrial sector, chemical resistance and mechanical stability are key advantages for parts exposed to harsh working conditions. This includes applications where the material’s ability to with- stand heat, oil and grease ensures longevity and reliability.


Composite innovation At the recent JEC World event, Arkema launched several innovations including Rilsan PA 11 – a bio-based solution for composites. Rilsan is used in to produce bio-based compos-


ites for transport, aerospace and sports applica- tions. With an optimised melting point, can be easily processed with natural fibres such as flax, hemp, and bamboo without degradation. Both polyamide 11 and natural fibres are derived from renewable resources, making these composites more sustainable and recyclable than traditional materials, says Arkema. The company also showcased its UDX tapes – which combine carbon fibres and bio-based thermo- plastic polymers. In addition, the HAICoPAS aerospace demon- strator showcased the performance of next-gener- ation thermoplastic composites. HAICoPAS is a technology demonstrator made


from HexPly thermoplastic composites, using Arkema’s Kepstan PEKK resin and Hexcel’s Hex- Tow® AS7 and IM7 carbon fibres. The material meets the needs of the aerospace industry, offering productivity gains and enhanced recycla- bility due to its thermoplastic nature. As part of this demonstrator, a continuous, dynamic in-situ welding (ISW) process has been co-developed by the Institut de Soudure and Arkema to meet the structural assembly needs of aerospace manufac- turers.


Raised temperature Temperature resistance is a property that often limits the use of plastics in applications such as automotive and electronics. The performance of materials such as PPA, PPS and Peek means they can be used in areas like ignition components and sensors for under hood components in cars, as well

as in sockets and coils in electronic systems. Automotive manufacturers also need to achieve more power from smaller engines – meaning they must run at higher temperatures. Eurotec offers several materials in this area. Its


Tecomid HT (PPA) and Tecotron XS (PPS) have continuous use temperatures (CUTs) of up to 180°C and 210°C. A 40% glass fibre-reinforced grade of Tecomid HT is being currently used by a leading automotive OEM for an inverter housing application – where standard PBT and PET cannot provide the required CUT. At the same time, 50% and 30% versions of this were designed for use in gear lever and high-heat lamp socket applications, respectively. A 30% glass fibre-reinforced grade of Tecotron XS has been used in thermal management systems such as a thermostat housing. Thanks to its thermal conductiv- ity and dimensional stability, a 65% grade of Tecotron XS has been used for an insulation coil application. For brush holders in E-motors, a 40%


reinforced version has been used. If a higher temperature is needed – such as in aviation – PEEK is typically the right material to withstand up to 260°C. Tecopeek grades


combine light weight, high thermal resistance and mechanical properties. Tecopeek PK40 CR30 BK111 is designed to


overcome corrosion issues and is used in metal replacement applications such as gears, bearing rings and pump components. Tecopeek PK40 CR30 BK111 RT 0D with a tensile strength of 23,500 MPa and 215 MPa is tailored to solve the problems equipment that operate under high temperatures and are exposed to constant wear, such as chain bushings in a textile machine. “We develop products that offer accurate solutions to our customers,” said Buket Turan, technical marketing manager at Eurotec.
