PTFE(Teflon)/PCTFE Flat Washers/Gaskets/Spacers

 

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.

 

 

We manufacture various different profile of PTFE seals include:

O-rings, back-up ring, guide/bearing ring, piston ring. rotary ring, valve seats, dipahragms, etc.

 

Material range:

100%virgin ptfe for light and medium load requirements.

 PTFE with filler( Glass/Graphite/Carbon/Bronze)for greater load requirements.

Virgin PTFE100% PTFE
Filled PTFEFiller Type
Inorganic fillerGlass fiber, Graphite, Bronze, Carbon fiber, MoS2
Organic fillerPolyimide, Aromatic Polyester, Polypheylene Sulfide 

Depending on applications, PTFE can be mixed with fillers to meet the requirements of application in order to provide the optimum sealing perperties.


Properties:

Excellent resistance to corrosion and chemical products
Wide temperature using range(up to 250 degree)

Low coefficient of friction
Self lubrication
Improvement in resistance to wear

Good sealing
