Belgian chemicals giant Solvay (Brussels; www.solvay.com) said it is speeding up delivery of a new generation of “Amodel” brand polyphthalamide (PPA) materials for the car industry. The materials are targeted at what the firm said were higher demands for performance and sustainability for advanced electrical and electronic applications in e-mobility.

The company noted that the “AE 9933” and “AE 9950” products from its “Supreme” range have been designed for e-motors and inverter busbars operating at 800 volts and higher.

Describing the materials as a breakthrough compared with conventional PPA technology, Solvay said the grades would also retain their comparative tracking index ratings – used to measure the electrical breakdown or tracking properties of an insulating material – over time “even after temporary exposure to peak temperatures above 150C”.

Meanwhile, Solvay said its new halogen-free flame retardant materials Amodel “Bios HFFR R1-133” and “HFFR R1-145” with a partially bio-based long-chain molecular structure provide UL94 V0 flammability ratings. The materials minimise the risk of electronic corrosion thanks to their halogen-free formulation, the company explained.
