General Industrial Grade PPA
General Industrial Grade PPA (Polyphthalamide) is a semi-crystalline high-temperature nylon material with excellent mechanical strength, stiffness, and heat resistance. This material maintains stable physical properties at short-term peak temperatures up to 255°C, with continuous use temperature ranging from 120-180°C. General Industrial Grade PPA exhibits excellent chemical resistance, low water absorption, and good dimensional stability, making it an ideal material to replace metals and traditional engineering plastics.
