Specification:

1:We can produce PTFE shaped parts for different usage. 
2:We can design according to customers' special demand or the drawings. 
3:We can supply PTFE machining products  filled with various other materials, such as bronze, carbon, glass fiber,and so on.


Filled PTFE 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
