Product Features

Main features of pure PTFE sheet :

1. Temperature resistance ---It is able to work stably between -180°C to +260°C.

2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.

3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.

4. Anti-aging, weathering resistance.

5. Excellent insulation property.

6. Filled material: Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.

Even if PTFE products have excellent properties, like high/low temperature resistance, chemcial resistance, weathering resistance, dielectric superiority and high lubricity, sometimes we still need to improve its hardness, wear resistance, creep resistance and dimensional stability.

Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.

Details of PTFE filled with other materials :

Filled materials	Common filled ratio ( Quantity %)	Main performances
Bronze	40, 60	Increases hardness and wear resistance; Increases dimensional stability and compressive strength;
Carbon	5, 10, 15	Increases compressive strength, hardness, wear, and load properties. Good chemical resistance;Improves electrical properties.
Graphite	5, 10, 15	Improves the deformation under load; Reduces initial wear; Improves thermal and eletrical conductivity
Glass Fiber	10, 15, 25	Increases compressive strength, rigidity and wear. Reduces creep and cold flow; Improve Dimensional Stability.
Carbon Fiber	10 , 15, 25	Increases compressive strength, hardness, wear, and load properties. Reduces creep and cold flow
POB (polyphenyl ester)	5, 10, 15	Improve the lubrication performance;Enhance the mechanical strength; Increase using temperature
BaSO4	5, 10, 15	Increases compressive strength, hardness and wear resistance Reduces creep
SiO2	5, 10, 15	Increases hardness and wear resistance; Improve Dimensional Stability.
Glass beads	5, 10, 15	Reduces creep and cold flow;Lower density Increases hardness and wear resistance;
Others materials	PEEK(polyetheretherketone), PI(Polyimide), MoS₂ are also ok
Remarks	Some materials have similar enhancement effect, but degrees of enhancement are different. And they have different prices. More details please contact us.
