Polytetrafluoroethylene(PTFE) Tube
HPTFE is made of imported polytetrafluoroethylene resin by pressing and sintering. It has excellent electrical insulation, high flame retardant, ultra-high temperature resistance, chemical agents and almost all oils and chemicals. It is widely used in transformers, electronic appliances, household electrical appliances and other industries.
