Detailed Product Description

As the typical type of fluoro plastic, PTFE and PVDF have the most excellent anti-corrosion performance among them. As the typical type of fluoroplastic, PTFE and PVDF have the most excellent anti-corrosion performance, among them PTFE is the best of all the plastic known to man, could be used in all the strong acid and alkali application, including HF and smoke formation H2SO4 HNO3 or HCL(98%)above).etc. and could be used in high temperature application. PTFE could be used to 180°C and PVDF to 150°C. But PTFE has very low mechanical strength, easy to be out of shape and have large Dimension change when the temperature rise or reduce. So they couldn't be used in heavy load and high-speed occasion. Compare with PTFD, PVDF has better competitive performance. Generally the rings and cage made with PTFE or PVDF, and balls made with glass, ceramic or stainless.
