PTFE bubble point film refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
PTFE bubble point membrane is a polymer compound of tetrafluoroethylene. It is one of the materials with the best corrosion resistance in the world. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand all other chemical reactions. , insoluble in strong acids, strong alkali and organic solutions, and does not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
However, because polytetrafluoroethylene is expensive and has lower strength than steel, it is generally made into linings, sealing materials and filling materials, and is protected and reinforced by a metal shell to form a whole.
In this way, the lining layer can resist corrosion and high and low temperatures, and the outer shell can withstand pressure and has sufficient strength and stiffness, which can reduce the overall cost.
Such as: corrosion-resistant pipes, containers, pumps, valves, radar, communication equipment, etc.
