Product Details

pps plastic raw material modified anti-static

PPS is a non-polar crystalline polymer with excellent electrical properties. It can be made into high-frequency electrical insulation materials, and has good electrical insulation properties in humid environments. The water permeability and air permeability of pps are low, and the shrinkage rate is large. Unmodified pps is not suitable for engineering parts. PPS has good fatigue and bending resistance, which can be bent 100,000 times, which is stronger than ordinary plastics and can be used as living hinges. PPS plastic products are very sensitive to the notch effect, so when designing products, you should try to avoid sharp angles, gaps, and large disparity. The tensile strength of pps is generally 21~39mpa, bending strength is 42~56mpa, compressive strength is 39~56mpa, elongation at break is 200%~400%, notched impact strength is 2.2~5kj/m2, low temperature notched impact strength It is 1~2kj/m2, Rockwell hardness is r95~105. The rigidity of pps is lower and the wear resistance is lower than that of pvc. pps has poor weathering resistance and must be an additive or ultraviolet absorber. Copper can also accelerate the aging of pps.

The use of fillers and reinforcing agents in pps makes it possible to take advantage of the high chemical resistance and stress cracking resistance of pps at high temperatures, as well as higher stiffness at room temperature. When the temperature is below 0°C, the brittleness of pps increases, and the use of fillers further aggravates it. In this case, the copolymer with ethylene has higher impact strength.
