PolyTetraFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE.
PTFE material has excellent resistance for all chemical corrosion. Its friction coefficient is the lowest in plastics.Temperature changes do not affect its electrical insulation property. So PTFE often be called "plastic king". PTFE is suitable for making corrosion resistant parts, wear parts, seal, insulation parts and medical equipment parts.
PTFE's mechanical properties are low compared to other plastics but its mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze.

1.Apply to one-piece piston.
PTFE backup ring are used for static and dynamic applications. It's better used for static sealing applications with corresponing O-ring.
The use of PTFE backup ring will help control O-ring extrusion in high pressure applictions. PTFE backup rings are compatible with all hydraulic fluids,since they are virtually chemically inert,and also can be used in applications involving elevated operating temperature conditions.In addition,PTFE backup rings can greatly improve O-ring performance and extend service life, even if extrusion does not present a problem.
