Waterproof PTFE Tape is produced with polytetrafluoroethylene, which is non-toxic, tasteless, with excellent sealing, insulation and corrosion resistance. It is widely used in water treatment, natural gas, chemical industry, plastics, electronic engineering and other fields. It is also used for filling the threaded end of pipe fitting, metal pipes and PCV pipes. Through mutual tightening, the sealing of the pipe fittings can prevent liquid leakage and pipe falling off.
