The remarkable properties of polytetrafluoroethylene (PTFE) are
well known, notably its low coefficent of fricition, non stick
surface characteristic, wide working temperature range from -180°C
- +260°C. excellet 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 flexbility high longitudinal strength, and easy
deformability in the transverse direction. makes expanded PTFE
unsintered tape very suitable for packing and threadsealing
applications. But it is not be suitable for use in certain critical
application for example when contact with high concentration of
gaseous oxygen or liqud oxygen involved.Expanded PTFE unsintered
tape is used for packing and thread sealing.
