PTFE Filter Cloth

The PTFE filter cloth is a strong acid and alkali resistant high temperature filter. Polytetrafluoroethylene is one of the best materials for corrosion resistance in the world today. It can be used for a long time in any kind of chemical medium! Polytetrafluoroethylene (PTFE) can be used in chemical, petrochemical, refining, chlor-alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas and other industries, as well as organic synthesis, non-ferrous smelting, steel, atomic energy and high Production of pure products (such as ion-exchange membrane electrolysis), transportation and operation of viscous materials, and processing and production departments of food and beverages with strict requirements for hygiene. Its suitable medium includes hydrofluoric acid, phosphoric acid, sulfuric acid, nitric acid, hydrochloric acid, various organic acids, organic solvents, strong oxidants and various other highly corrosive chemical media. Its applicable temperature is -20 ~ 250 ° C, allowing quenching and rapid heat, or alternating hot and cold operation. The PTFE filter uses plain weave technology.
Characteristics of PTFE filter cloth
Corrosion resistance: It can withstand all kinds of strong acids (including aqua regia), strong oxidants, reducing agents and various organic solvents in addition to molten alkali metals, fluorinated media and sodium hydroxide above 300 °C.
Insulation: It is not affected by the environment and frequency. It has low dielectric loss and high breakdown voltage.
High and low temperature resistance: The effect on temperature is not changed much, and the temperature range is wide.
Weathering resistance: It has radiation resistance and low permeability. It can be exposed to the atmosphere for a long time, and its surface and properties remain unchanged.
Non-combustible: The oxygen limit is below 90.
