Трубка из ПТФЭ большого диаметра для электрической

PTFE materials be discovered by Mr.Roy J.Plunkett in a Freon experiment at 1936.We can say,it is a precious gift he give all mankind. After many years research,people find more and more usage in Chemical/Machine/Petroleum/Electricity industry etc, environmental protection and daily living equipment.

PTFE also named “TEFLON”.

People called “ plastic king”. The Engilsh spelt is “Polytetrafluoroethylene” . This materials with many excellent characteristic. It has the best chemical resistance[in all known plastic],the lowest friction coefficient,the best electrical properties and UV resistance.

Our company purchase the world famous raw materials brand,such as “Daikin”, “Do Pont”,”Dongyue”,”CHC”,etc.

High voltage cable protect tube--- The PTFE tube can be used as a protective sleeve for high voltage cables with the excellent electrical resistance of PTFE materials. The breakdown strength of the PTFE insulating sleeve is up to 200kv/mm.At same time, Polytetrafluoroethylene is very stable to arc action, usually arc resistance is greater than 300s. This is because when the surface is discharged at high voltage, it will not cause short circuit due to carbonization, but only decompose into gas. Even in the long open air exposure, it is not affected by the dust and rain. The insulation resistance of polytetrafluoroethylene is very high, the volume resistivity of P V is generally greater than 1015 Omega m, the surface resistivity of P S is greater than 1016 Omega, even if it is dipped in water for a long time, it is not significant, and it is not changed with the temperature.
