PPA
(Polyphthalamid)
Polyphthalamide (PPA) is a semi-crystalline and partially aromatic polyamide that has a high temperature resistance. The PPA remains very stable both at high temperatures and in a chemically aggressive environment and continues to have excellent mechanical and electrical properties. PPA is mainly used as a substitute for metals that require high temperature resistance.
