Stainless steel corrosion resistant bearings, stainless steel as a matrix, the middle of the sintering corrosion resistant alloy powder, the surface of the rolling ptfe based low friction materials, after the rolling molding of a very effective corrosion resistant materials.It has the characteristics of oil resistance, acid resistance, alkali resistance, seawater resistance and wear resistance. The PTFE material on the surface does not contain lead.
In food and beverage machinery, chemical medium ph flow of the pump valve, pharmaceutical machinery, printing and dyeing machinery, chemical machinery, Marine industry corrosion resistance sliding parts are most suitable for use.

It is a polymer made of tetrafluoroethylene as monomer.White waxy, translucent, good heat and cold resistance, can be used in -180 ~ 260 C for a long time.This material has the characteristics of anti - acid, anti - alkali, anti - various organic solvents, almost insoluble in all solvents.At the same time, ptfe has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become easy to clean the ideal coating of the inner layer of the water pipe;Toxic, human carcinogen.
