Polyphthalamide (PPA) is an aromatic polyamide that outperforms standard polyamides with higher strength and stiffness at elevated temperatures, better retention of properties in humid environments, and greater resistance to a broader range of chemicals.
PPA is used to replace metal in high-temperature automotive applications. Continuous-use temperatures range from 120°C to 185°C (248°F to 365°F). Heat deflection temperatures (HDT) go up to 310°C (590°F).
Properties : PPA has advantages of high modulus, high rigidity, high performance price ratio,
low water absorption rate, dimensional stability and excellent weldability etc. PPA material has excellent overall properties which enable its well performance under thermal, electrical, physical and chemical condition. PPA still maintains high rigidity & strength, as well as excellent dimensional accuracy & stability even under high temperature.
Engine cooling: thermostat housings, inlets/outlets, water pumps, chargeair coolers.
