Guangzhou Dong Wang Rubber Products Co., Ltd. PTFE membrane manufacturer tells you: polytetrafluoroethylene is tetrafluoroethylene polymer. English abbreviation for PTFE. Under the trade name "Teflon" (teflon). Known as the "king of plastic." The basic structure of PTFE is -. CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 -. PTFE is widely used in a variety of organic solvents and the need for anti-acid, it is itself is not toxic to people, but one of the raw materials used in the production process of ammonium perfluorooctanoate (PFOA) is thought to be carcinogenic. PTFE membrane manufacturer main products are high temperature PTFE film, Teflon film, imported Teflon film, filled Teflon film, color fluorine plastic film, white PTFE film, shaped Teflon film Guangzhou City East Wang Technology Co., fluorine plastic Teflon 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, but also almost insoluble The vast majority of the solvent, only slightly soluble in the above 300 ℃ Full alkanes (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.
