Material plastic PPA is stronger and harder than polyamides such as nylon6, and 66, etc.Lower sensitivity to water;Better thermal performance;And creep, fatigue and chemical resistance are much better.
PPA material has excellent combination properties, which performs well at thermal, electrical, physical and chemical properties. Especially under high temperature PPA still has high rigidity and high strength, together with excellent dimensional accuracy and stability.
Special using grade for Automotive water temp control assembly and thermostat body part.
