PTFE Guide Tape:
PTFE product includes sheet, Tube (ZR-48), Rod (ZR-49), Film (ZR-47) and gaskets etc., they are molded, skived or cut from 100% virgin PTFE. It has the best chemical corrosion resistance among known plastics. Without being aging, lowest friction coefficient, wear resistance. The unloaded operating temperature range is -180~+260C.
PTFE guide tape is made of Pure PTFE or filled PTFE materials ,
Polytetrafluoroethylene (PTFE) has a melting point of 327 degrees C, a density of 2.18-2.3g/cm3 and a Shaw hardness of D50-65. It has excellent chemical stability and self-lubrication. It is the most widely used and used variety of fluorinated plastics. It has excellent comprehensive properties, such as high and low temperature resistance, corrosion resistance, aging resistance, non-adhesion, high insulation, high lubrication and non-toxicity. But PTFE has poor creep resistance, poor wear resistance and high expansion coefficient, so filling modification is usually needed to overcome these shortcomings. Commonly used fillers are copper powder, carbon fiber, glass fiber, graphite, molybdenum disulfide, polyphenyl ester, polyether ether ketone and so on. According to different working conditions and uses, one or more substances can be filled.
