The Advantages of PTFE/Teflon Lined Valves
PTFE is commonly known as "plastics king". It was developed by the American DUPONT CO., LTD in 1938. The industrial production of it began in 1949. From the perspective of industrial applications, it has existed for 50 years. But it’s not long for the widely application.
In anti-corrosion materials, Teflon has the incomparable outstanding performance. In addition to smelting alkali metals, elemental fluorine and aromatic categories, it can also react mildly with various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acids, strong oxidants, thick, alternating acid, alkali, and various organic solvents. Lining with Teflon lining on the internal wall of valves can not only overcome the lower intensity of PTFE but also can solve the problems of poor corrosion resistance, high cost deficiencies of the valve materials. In addition to the excellent chemical stability, the PTFE also has some other advantages: good anti-fouling, anti-sticking performance, small dynamic and static friction coefficient and good Anti-friction and lubricating performance. Therefore, it can be used as the sealing pairs for the opening and closing parts of valves. It can also be used in the food and pharmaceutical industries.
