prototype shown at K2019 addressed the perceived shift in emphasis in future automotive interiors from driving to traveling environments. It combined Maezio sheet with the company’s Baynat PU-based acoustic foam. The company has also partnered with the
Research and Development Center of Guangzhou Automobile Group (GAC R&D Center) to develop a lightweight composite seat back for the Chinese car manufacturer’s latest electric concept car, the ENO.146. With a drag coefficient of 0.146, GAC says the
ENO.146 is one of the most aerodynamically efficient vehicles in the world and aims for an NEDC (New European Driving Cycle) range of 1,000km. While the aerodynamic design is key to achieving that performance goal, the GAC R&D Center also uses lightweight materials to reduce weight. The backrests of the two front seats of the concept car are made from Maezio carbon-fibre reinforced thermoplastic, which is estimated to save up to 50% in weight compared to typical metal constructions. The car will become a multifunctional, mobile living and working space. The concept focuses equally on functionality, comfort and design, but also on efficiency and light weight. The focus is on multi-sensor infotainment systems, innovative seating concepts, smart surfaces and personalised lighting. Other Covestro developments include an
integrated, three-dimensional multifunctional large-format display concept produced using In Mould Decoration (IMD) and Film Insert Moulding (FIM) technology and its Makrolon AI PC compounds and Makrofol PC film. It says that polycarbonate films may serve as a mouldable carrier for printed electronics, enabling the integration of additional functions.

Cooling performance Automotive electrification opens up new fields of application for high performance polymer com- pounds, according to Evonik, which offers PA12, PI and PEEK materials. It says both hybrid and fully electric vehicles require highly effective cooling systems, not only for the high-voltage battery but also for other essential high-voltage components such as the motor and converter or inverter. In addition to mono-layer tubing based on its Vestamid PA12, Evonik has developed its MLT 8000 multilayer tubing system for such thermal manage- ment applications. The company also sees opportunities in motor and drive systems. Specialised products such as Vestamid PA12, P84NT PI and Vestakeep PEEK compounds allow manufacturers to produce durable components, such as bearings or gears. Their use reduces friction for efficient, long-term use and eliminates noise and vibrations. Quick charging times are also the key to successful electromobility. New standards allow for charging up to 350 kW, which reduces charging time to minutes but places high demands on materials. The company says its flame-resistant Vestamid PA12 and durable Vestakeep PEEK are suitable for use as insulation for cables or busbars in the battery module or electric motor, and as plug components for the high-voltage charging and on-board system. Long glass-fibre reinforced Grivory GVL-4H V0 and Grilamid L PA grades from EMS-Grivory are being used in a rapid charger developed by Swiss cable company Huber+Suhner. The RADOX HPC high power charging system operates at up to 400A and 1000V, which allows the batteries of larger electric vehicles to be charged to 80% in less than 15 minutes. It is already in use in North American and European rapid charging networks. The charger uses the flame-retardant EMS-Grivory LFT for the car charging station system, which is designed for rough daily use, while the Grilamid L grade is used in the charging system’s active liquid cooled cable.
