Expanded PTFE sheet is manufactured by technique of compacting, sintering, rotary cutting with PTFE granular resin. It has good dielectric performance and non-aging, best anti chemistry corrosion ability and wide applying intension range.
Expanded PTFE sheet is manufactured by molding process with PTFE regular resin and sintering.It is very suitable for seals,lining,diaphragm,spacer guide and bearing pad for bridge.

Main Features
1. Heat resistance property---It is able to wok stably between -180°C to +260°C.
2. Excellent non-sticky property---It easier to remove those resin, dopes, oil and other sticky things.
3. Good mechanical property with no distortion and low friction coefficient.
4. Excellent insulation property.
5. Materials like carbon, graphite and glass fiber can be filled.
6. Virgin and recycled materials are available

Details
PTFE resin,filled with some filling stuff,can prolong the life of
products and strengthen the performance,eg:Graphite,Carbon ,Glass fiber
,bronze
Glass Fiber: |
Increases compressive strength, rigidity and wear. |
Carbon: |
Increases compressive strength, hardness, wear, and load properties. |
Graphite: |
Reduces coefficient of friction |
Molybdenum Disulfide: |
Increases hardness, stiffness, and wear |
Bronze: |
Increases hardness and wear resistance |
