Enhance Wear Resistance Filled PTFE Products

Enhance Wear Resistance Filled PTFE Products

PTFE has outstanding excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties and low friction coefficient. Adding any filler that can withstand the sintering temperature of PTFE in PTFE can greatly improve its mechanical properties. . At the same time, maintain other excellent properties of PTFE. The filled varieties are glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, etc....

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.

Main performances 

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

Carbon Fiber

10 ,  15,  25

Increases compressive strength,   hardness, wear, and load properties. 
 
Reduces creep and cold flow

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.
