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. Meterial: 100%virgin ptfe for light and medium load requirements. PTFE with filler( Glass/Graphite/Carbon/Bronze)for greater load requirements. PTFE seal Properties: 1.Working temperature:-180~+260°C 2.Melting point:327°C 3.Yield strength: 23MPa 4.Density: 2.2-2.3g/m3 5.Coefficient of friction<0.10 6.Strong chemical-resistant
