PPA has high hardness, excellent mechanical strength such as bending, tensile and impact at high temperatures, and can resist tensile creep for a long time. At a high temperature of 120℃, its rigidity and strength even exceed PPS and PEEK. It is particularly suitable for replacing die casting alloys to reduce costs.

 

PPA has higher thermal stability than PA46, better CTI arc resistance and infrared reflow welding capability. PPA has excellent resistance to gasoline, diesel, oil, mineral oil, transformer oil and other oils, even at 150 ° C high temperature. PPA even in extreme climate conditions such as high ultraviolet radiation, high humidity, and high temperature, it is suitable for long-term outdoor use without causing a reduction in physical properties.

 

PPA material properties

 

1.PPA is a kind of high temperature resistant material, its melting point is between 310-325℃, and the thermal deformation temperature is between 280-290℃.

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

3.PPA has excellent dimensional stability and low warping

4. The water absorption rate of PPA is much lower than that of PA6 or PA66, and its tensile strength can be maintained above 80% even if it is soaked in cold water for several years

5.PPA has excellent weather resistance and is also suitable for long-term outdoor use under extreme climatic conditions such as high UV radiation, high humidity and high temperature 6.PPA has superior environmental performance and can reach the US FDA level
