tions tailored to the requirements of customers. Materials company Solvay has developed a new
generation of its Amodel polyphthalamide (PPA) materials targeted at higher demands of perfor- mance and sustainability for advanced electrical and electronic applications in e-mobility. The Supreme range, comprising Amodel PPA AE 9933 and AE 9950, has been designed for e-motor and inverter busbars operating at 800 volts and higher. The company claims its grades combine best-in-class CTI ratings with high thermal cycle shock resistance from -40 to 150°C. In what the firm considers a “breakthrough” unlike conventional PPA technology, the new grades will reportedly retain their CTI over time, even after temporary exposure to temperatures above 150°C. The company has also introduced halogen-free
flame-retarding grades, Amodel Bios HFFR R1-133 and HFFR R1-145. These are to meet the growing trend of integration of e-motor, power electronics and gearbox into a single, consolidated electric drive system. With a CTI greater than 600 volts, heat resistance greater than 120°C and good claimed dimensional stability, these grades enable the design of highly compact systems using miniaturised components. Although halogen-free, the two grades are UL94 V0 flammability rated. As well as addressing safety concerns, in the event of uncontrolled thermal excursion, the halogen-free formulation also minimises the risk of electronic corrosion. Amodel PPA Bios features a partially bio-based long-chain molecular structure which the company claims has the highest glass transition temperature (Tg) as well as the lowest global warming potential
Solvay has launched Amodel Supreme and Bios grades for e-mobility applications
(GWP) compared to existing bio-sourced long- chain PPAs.
Brian Baleno, Head of Marketing, Automotive at Solvay Specialty Polymers, says: “Amodel Supreme and Bios are garnering a high level of interest among designers of e-propulsion systems, includ- ing e-motors, power electronics, and electronic coolant pumps. Beyond adding value by improving the thermal and electrical performance of e-mobili- ty components in these systems, the new additions to the Amodel polymers family are being more widely considered as manufacturers are seeking to meet ambitious sustainability targets.”
