Solvay Specialty Polymers has expanded its Amodel AE-8900 series of products for automotive electronics applications by adding five new glass fiber-reinforced grades with glass filler ranging from 30 to 60%.

The new Amodel polyphthalamide (PPA) materials provide high voltage resistance and retention of dielectric properties at elevated temperatures. They also delivering greater resistance to automotive fluids, enhanced thermal properties, higher mechanical strength and lower moisture absorption when compared to others in the range, the company says.

‘Automotive design engineers are intensely focused on greater electrification of the drivetrain in order to meet upcoming carbon dioxide emissions standards in Europe and emerging corporate average fuel economy (CAFE) standards in the United States and China,’ said Brian Baleno, global automotive business development manager for Solvay Specialty Polymers. “Our new Amodel AE grades [expand] the range of advanced materials that meet or exceed critical design criteria for these emerging electronic drive systems.’

Solvay’s Amodel AE-8900 series includes AE-8930, AE-8935, AE-8940, AE-8950 and AE-8960 grades, which have 30, 35, 40, 50 and 60% glass fiber reinforcement respectively.

Amodel AE-8935 provides the best crack resistance during thermal shock testing of any commercial PPA product, Solvay says. This grade, along with Amodel AE-8940 PPA, meets design criteria for emerging automotive technologies, such as electric motors, fuel cell vehicles and power electronics.
