Customized White 15 % / 25 % Glass Fiber Filled PTFE Washer Flat Gasket Shim with Thickness 0.03-1.0 mm
Description
Reinforced PTFE material has excellent resistance for all chemical corrosion. Its friction coefficient is the lowest in plastics. Temperature changes do not affect its electrical insulation property. So PTFE often be called “plastic king”.
PTFE is suitable for making corrosion resistant parts, wear parts, seal, insulation parts and medical equipment parts.
| 1. Usage | A. Electrical insulation parts B. Sealing parts C. Automobile parts D. Corrosive fluid conduit E. Connector accessories |
| 0.02mm |
| A. Flat and tidy B. No defects of crevices layers and separation |
| -196℃ to +260℃ |
| A. Aging resistance B. Radiation resistance C. Low permeability D. High pressure resistance E. Oil resistance F. Anti-corrosion |

Remark: even if PTFE products have excellent properties, like high/low temperature resistance, chemical 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, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.
PTFE is recommended for:
Chemical environments
Use is acidic or basic environments
Sealing of moving or sliding surfaces
PTFE is not recommended for:
Low compression vacuum sealing flanges
High vacuum seals
High temperature steam
