PTFE thread seal tape
Description
The remarkable properties of polytetrafluoroethylene (PTFE) are well known, notably its low coefficient of friction, non stick surface characteristic, wide working temperature range from -180¡ãC - +260¡ãC. excellent weathering resistance and corrosion resistance.
Expanded PTFE unsintered tape makes from pure PTFE. It has an expanded network composed of superfine fibers and joints. The combination of flexibility high longitudinal strength, and easy deformability in the transverse direction. makes expanded PTFE unsintered tape very suitable for packing and thread sealing applications. But it is not be suitable for use in certain critical application for example when contact with high concentration of gaseous oxygen or liquid oxygen involved.
