High performance bio-based PIN polyphthalamide

Dupont has launched a new non-halogentated flame retardant, bio-based polyphthalamide (PPA) compound for electrical components, including SMT connectors (surface mounted component). PPA (polyphthalamide) are aromatic polyamides. The compound can replace metals, performance polymers such as such as LCP (Liquid Crystal Polymers) and thermoset polymers in sectors including automotive and electronics, in components such as circuit breakers, connectors and miniaturised electronics. Safety qualities include UL94-V0 fire performance at 0.4 mm, GW (glow wire flammability) standards and high CTI (comparative tracking index). The material offers operational reliability at elevated temperatures and humidity, and processing advantages including high flow, low mold deposit and no equipment corrosion, good weld line strength and high temperature soldering resistance up to 280°C.
