PTFE O Ring Gaskts with High Chemical Resistance Back Up Ring

The PTFE Seal consist of a PTFE sealing element and a rubber O-ring functions as elastic energizer. The required sealing effect is achieved by radial pressure, produced by the preloaded element and system pressure.

Outstanding features of PTFE Seal are:

wear resistance can be improved by proprietary fillers
very good in sealing most of chemicals
high extrusion resistance
good thermal conductivity (ranging from -450 deg F to +600 deg F)
easy fitting

Application:

low break-out and low friction hydraulic cylinder
low friction and no stick-slip pneumatic cyclinder
Plunger
Cyclinders in corrosive environment
Low friction cyclinders in high-temperature application
Cylinders for machine tool and construction equipment
Cylinders for press/ extrusion/injection molding equipment
Cylinders for precise control application

Poly Tetra Fluoro Ethylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE.

It offers high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation.

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.

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is also known by the common trade name , which is trademarked by DuPont. PTFE can be modified for use as a gasketing material with strong chemical resistance properties. It can also be machined or molded into most any shape.

PTFE O-RINGS

PTFE is a superior O-Ring material not affected by most chemicals. It can be used at temperatures up to 500°F (260°C). It has the lowest coefficient of friction of any solid material. Lubrication is less critical and can sometimes be omitted.

O-rings can be made 100% from PTFE or elastomers silicone or nitrile can be coated in a PTFE sheath for added chemical resistance while maintaining maximum flexibility.
