Large PTFE Gasket Heat Resistance Elastomeric With Good Mechanical Properties

PTFE / Seals Heat Resistance O Ring Seals Used in Truck

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.

Benefits of PTFE Seals:

1. Simple installation
2. Low stick-slip
3. High media compatibility
4. Low friction at high pressures and speeds
5. High abrasion resistance

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.

PTFE parts

PolyTetraFluoroEthylene 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.
