BASF has developed a new range of flame retardant polyphthalamide (PPA) materials with im-proved electrical insulation.

According to the company, the grades have high electrical relative thermal index (RTI) values above 140°C and are halogen-free according to EN 50642. Non-halogenated PPAs based on polyamide (PA)9T, PA66/6T, PA6T/66 and PA6T/6 also allow for better colorability and long color stability, BASF said.

Materials can be used in applications such as connectors for power or data transmission in vehicles, appliances and consumer electronics, e-mobility parts, miniature circuit breakers, switch gears and sensors.

The compounds are available with short-glass, long-glass or mineral fiber reinforcement, and with various heat stabilizers.
