Polyphthalamide (PPA)

PPA (Polyphthalamide) is a high heat resistant semi-aromatic polyamide. As a member of the nylon family it is a semi-crystalline material composed from a diacid and a diamine. With its heat resistant and low moisture absorption properties, PPA is ideal for use in a chemical environment or temperature extreme conditions. Common applications include automotive motor bobbin parts, fuel line connectors and coolant pumps as well as bushings and bearing pads in aircraft engines. PPA is also used for pump wear rings in the oil & Gas and energy industries.
