The material ensures high reliability for high-voltage parts that do not gain enough creepage distance. Water and salt can penetrate high-voltage parts and cause tracking issues; so materials with high CTI values are required. Polyplastics also offers DURAFIDE (R) PPS 6150T73, which provides high heat shock resistance, strong dimensional stability, and excellent heat and chemical resistance for metal insert molded applications for electric vehicles. Previous material technologies suffered from lower heat shock resistance when moldability (flowability) increased. Polyplastics is also exploring new materials to replace metal in PCU housings. Thermoplastics would provide lighter weight and improved productivity. However, other key requirements include strength, dimensional stability, electromagnetic shielding and thermal conductivity. Specifically, Polyplastics is currently developing materials with electromagnetic shielding properties. The company is also targeting its material development work for other EV applications such as motors and batteries.
