| PPS/PTFE-hGR203 is lubricant PPS compound, which is filled with glass fiber, PTFE and ingredients based on the PPS resin. It shows solvent resistance, abrasive resistance and good mechanic prosperity, high modulus, creep resistance, high-temperature resistance, inherent flame resistance, easy processing, low mold shrinkage, good dimensional stability. Owing to its high performance, it’s widely used in mechanical and chemical industry for making wearable parts/components which work in the high-temperature, high pressure and solvent circumstance. Such as: plastic axle bearing, axle sleeve, textile machine components, components which are used in aero industry.&& |
