BASF flame-retardant polyphthalamides

BASF is expanding its polyphthalamide (PPA) range with a variety of flame retardant grades that combine high thermal stability with excellent electrical insulation and low water uptake. They are characterised by high electrical relative thermal index (RTI) values above 140° Celsius while being halogen-free according to EN 50642, thus preventing corrosion and failure of electrical parts when used under moist conditions.

The flame retardant grades are suitable for applications like connectors for power or data transmission in vehicles, appliances and consumer electronics as well as for e-mobility parts, miniature circuit breakers, switch gear and sensors.

All the flame retardant materials in the PPA portfolio keep their high mechanical and dielectric strength at elevated temperatures. They show dimensional stability due to low and slow water uptake as well as a low coefficient of thermal expansion. They allow for V-0 rating at thicknesses down to < 0.4mm and are in agreement with the cable management standard CMS EN 50654 (2018-05).
