PPA compounds can replace metal

Solvay has launched a new line of polyphthalamide (PPA) compounds suitable for e-mobility and metal replacement applications.

Amodel Supreme PPA can be used to make high-temperature automotive components used in electric drive units including e-motors, power electronics, housings for high-temperature electrical connectors, electric and electronic devices and telecommunication equipment components that need excellent heat resistance, the company said.

Solvay’s Amodel Supreme PPA can also reportedly replace metal in more traditional and structural applications such as clutch cylinders, shift forks and body in white.

According to the company, the material has glass transition temperature (Tg) of 165°C which enables a higher mechanical performance when compared to traditional polyamide (PA)4T and PA6T based materials at elevated temperatures. There is also a greater coefficient of linear thermal expansion (CLTE) match to metals that allows for ease in designing overmolded components.

Amodel Supreme PPA also has improved electrical properties, volume resistivity and dielectric strength above 150°C.
