High Temperature Nylon PPA’s Characteristics and Main Applications

PPA material performance characteristics

1, PPA is a high temperature resistant material, with melt point between 310-325°C and a heat distortion temperature (HDT) between 280-290°C.

2, PPA has excellent oil resistance and excellent resistance to various oils such as fuel oil and lubricating oil, even at a high temperature of 150 ℃

3, PPA has excellent dimensional stability and low warpage

4, The water absorption rate of PPA is much lower than that of PA6 or PA66, and its tensile strength can remain above 80% even after being immersed in cold water for several years

5, PPA has excellent weather resistance and is also suitable for long-term outdoor use under extreme weather conditions such as high UV radiation, high humidity, and high temperature.

6, PPA has excellent environmental performance and can reach the US FDA level
