Teflon membrane made of sodium _ Conghua Teflon membrane Na _ East Wang Technology Certified

Guangzhou Dong Wang Rubber Products Co. www.donghong-ptfe.cn PTFE film (Teflon or PTFE), commonly known as "plastics king", Chinese trade name "Teflon film," "Teflon film" "Teflon film," "Teflon film," and so on. It is made by polymerization of tetrafluoroethylene polymers, it has excellent chemical stability, corrosion resistance, tightness, high lubrication viscosity, electrical insulation and good anti-aging endurance. + Long-term work temperature is 250 ℃ to -180 ℃ under, in addition to the molten metal and liquid sodium fluorine, the ability of all other chemicals, boiling water does not play the king change Our main business: Teflon film tape, PTFE film, high temperature Teflon film tape, oil Teflon film, directed Teflon film, Teflon film imports, quality Teflon film Teflon film and other fluorine plastic Guangzhou City East Wang Technology Co., polytetrafluoroethylene Fluoride has a very high chemical resistance, for example, concentrated sulfuric acid, nitric acid, hydrochloric acid, boiling water and even the king, no change in its weight and performance, and almost insoluble in most of the solvent, only slightly above 300 ℃ Full alkanes dissolved (about 0.1g / 100g). PTFE does not absorb moisture, flammable, oxygen, ultraviolet rays are extremely stable, and therefore have excellent weather resistance. It is worth noting that the polytetrafluoroethylene can not tolerate reducing atmosphere extremely molten alkali metal, an alkaline solution of ammonia (alkali metal in liquid ammonia), some fluorides (e.g., TFA), etc. can be quickly sodium naphthalene Corrosion electrical properties of PTFE Teflon products dielectric constant and dielectric in a wide frequency range of losses are low, and the breakdown voltage, volume resistivity and arc resistance are high. Radiation resistance radiation resistance of PTFE is poor (104 rads), after degradation caused by high-energy radiation, electrical and mechanical properties of the polymer were significantly decreased.
