According to its temperature tolerance we can divide Teflon tape into two sections, one is high temperature resistant tape 260 degrees, the other is high temperature resistant tape 180 degrees.
PEFE tape is a kind of high-performance, multi-using composite product. Because of its excellent performance, it is widely used in paper making, food, environmental protection, printing and dyeing, clothing, chemical industry, glass, medicine, electronics, insulation, grinding wheel slicing, machinery, etc. Main features: high temperature resistant: in the temperature range of -70 °C-260°C it works continuously for 200 days without losing weight or strength, when it is placed at a high temperature of 350 °C for 120 hours, it only reduced weight about 0.6%, it will maintain the original softness at ultra-low temperature -180 °C.
There are some customized Teflon tape, which are made from customized high temperature resistant fiber glass cloth and high temperature resistant Teflon emulsion under special production technology. They are higher temperature resistant than we said just now.
Different grades of Teflon tape with different temperature limited, their price will be much different, you should figure out which temperature you will use before buying high temperature Teflon tape.
