PPA

PPA (Polyphthalamide) filament is a high-performance semicrystalline polyamide with higher temperature resistance, stiffness and strength than standard nylon. It offers excellent mechanical properties, low moisture absorption versus PA, and good chemical resistance. Requires high nozzle temperature and enclosed chamber, moisture sensitive. Suitable for high-strength gears, structural automotive parts, engine-adjacent components and high-temperature mechanical brackets.
