Because of the pronunciation, it is usually called Teflon, Teflon, Teflon, and Teflon. Long and so on (all are the transliterations of Teflon). Teflon (Teflon) coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction. It has comprehensive advantages that other coatings cannot compete with. It is flexible in application. The sex makes it can be used on almost all shapes and sizes of products.
Teflon can be used in the production of rods, tubes, plates, cable materials, raw material tapes and other materials. After secondary processing, it can also be made into thin plates, films and various special-shaped products. It can also be used as a lubricant and thickening agent.
