We can supply PTFE products  filled with various other materials, such as bronze, carbon, glass fiber, and so on.

PRODUCTS FEATURES:
1.Low temperature and high temperature resistance (-190 °C- +250 °C)
2.corrosion resistance , weather resistance
3.high lubricity, no adhesion
4.non-toxic,
5.non-flammable
6.acid and alkali resistance (except molten alkali metals)
7.antioxidant.

FILLED MATERIAL:
Glass Fiber: Increases compressive strength, rigidity and wear.Reduces creep and cold flow, Minimal effect on chemical and electrical properties
Carbon: Increases compressive strength, hardness, wear, and load properties. Good chemical resistance, Various types and amounts of carbon can be added to alter conductivity
Graphite: Reduces coefficient of friction, Reduces initial wear, Increases strength, Molybdenum
Disulfide: Increases hardness, stiffness, and wear,Minimal effect on chemical and electrical properties
Polybenzoate: Improve the creep resistance, dimensional stability, high temperature;
Bronze: Increases hardness and wear resistance, Increases dimensional stability and compressive strength,Not suitable for corrosive or electrical applications
Silicon Disulfide:  Improve wear resistance, dimensional stability and chemical resistance.
