Product Description

Graphite Filled black color PTFE rings used as self lubricating seal
Filled PTFE ring has strong corrosion resistance and friction-resistance, By adding filler such as glass
fiber, carbon fiber, copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder, ceramic fiber, metal
powder, polyamide, PS, the hardness, compression strength and abrasion resistance of the products is
improved ,in addition, it will have good heat conductivity and low heat expansion coefficient.

1. Low water absorption

2. Corrosion resistance

3. Temperature resistance

4. High diaphaneity

5. Voltage resistance

Property of PTFE
Of all the known plastics, PTFE has some remarkable properties: it will not attacked by corrosive acids, even if they were hot; it did not dissolve in
solvents; it could be cooled to -180°C without becoming brittle and it could be heated to 260°C without impairing its performance. PTFE materials
also are extremely stable and nonflammable; clean, dry, non-oily and non-staining. The material is biologically inert and does not support
biological growth (that is, it is non-pyrogenic). PTFE offer an extremely low static coefficient of friction, which stems from the extremely low
intermolecular forces in the PTFE molecule itself.
Apparent Density: 2.1 ~ 2.3 g/cm3
Tensile Strength: ≥ 14.0 Mpa
Ultimate Elongation: ≥ 140%
Temperature: -20° F to 500° F (-180°C to 260°C)

Customized carbon powder filled PTFE products
A certain amount of carbon powder filled into PTFE mainly improves the wear resistance, thermal conductivity and creep resistance of PTFE. It can be widely used in hydraulic and pneumatic seals, guide rings, piston rings, retaining rings, bearing sleeves, bearing shells, etc.
Carbon fiber filled PTFE products
Carbon fiber PTFE has the advantages of good chemical resistance, high mechanical properties, strong damage resistance and high temperature resistance. The production technology is relatively mature. It can be widely used in pneumatic seal, guide ring, bearing bush, sleeve, piston ring, guide rail, military products and other industries. It is also suitable for use in the presence of aqueous media.
