Dongguan Changyong Win Insulation Material Co., Ltd. is a private high-tech enterprise specializing in the production of PTFE film and other PTFE insulation products. The following is a description of its product characteristics and application fields:

1) The pore size of the membrane can be adjusted to obtain different bubble point pressures to meet different filtration accuracy.

2) uniform membrane pore size distribution, to ensure complete retention of bacteria and other impurities.

3) extensive chemical applicability, biological safety and pyrogen control.

4) Hydrophobic and hydrophilic 2 categories:

Hydrophobic: used for gas filtration to achieve sterility, large flux, high temperature resistance, strong acid and alkali resistance, wide chemical applicability, suitable for fermentation tanks, carbon dioxide, nitrogen, compressed air. When used for gas filtration, it can reach 100% retention of various bacteriophages, bacteria and particles above 0.2um.

Hydrophilicity: used for liquid filtration to achieve sterility, wide chemical applicability, strong acid and alkali resistance, high ozone strength.

5) Biosafety: After 100% integrity test, it has reached the requirements of HIMA bacterial interception test in the United States.

Teflon film

Suitable for electrical, electronic, aviation, aerospace capacitor dielectric wire, electrical instrument insulation and chemical corrosion and gasket lining.
