PTFE heat shrinkable sleeve is made from PTFE resin and prepared by paste extruding and blowing technique. It has the properties of non-sticking, anti-corrosion, anti-abrasion, ultraviolet resistance and high ultraviolet light transmission, and also has good dielectric property. Its heat shrinkage temperature is about 330 and its shrinkage rate in the following table. It can be used as high-class dielectric insulation and protective material at the temperature range of 200 through 260. It conforms to the enterprise standard Q/GHAD 80-2007.
