The Temperature Of PTFE Heat Shrink Start To Shrink

                                 the temperature of PTFE heat shrink start to shrink

Usually there is a lot of custom who asked us the shrink temperature of PTFE heat shrink tube.

The normal operating temperature of Teflon heat shrinkable tube is - 65 ℃ ~ 260 ℃ and it can work normally for two hours at 300 ℃.


it is a  very high work temperaure, but the wire which used the PTFE heat shrink tubing cann;t work understand such high temperature. so the need to know the best shrink temperature of PTFE heat shrink tubing.


for 1.7:1 PTFE heat shrink tubing, its shrink temperature is 280 degree C. for 4;1 PTFE heat shrink tubing, its competely shrink tube is up to 450 degree C.


so please according the wire you use choose suitable heat shrink tubing. also we introduce FEP heat shrink tubing and PFA heat shrink tubing for you. its shrink temperature is much lower than PTFE's


Teflon heat shrinkable tube is made of high quality Teflon [PTFE polytetrafluoroethylene] by extrusion and sintering:


Teflon heat shrinkable tube not only has the common advantages of ordinary heat shrinkable tube, but also has the excellent characteristics of fluoropolymer.


Teflon heat shrinkable casing is made of the best polytetrafluoroethylene in fluoropolymer.


The advantages of Teflon heat shrinkable casing are: high temperature resistance, chemical corrosion resistance, not easy to be broken, low moisture absorption, rapid and complete shrinkage at high temperature.


Polytetrafluoroethylene heat shrinkable pipe has excellent electrical insulation, high flame retardant and self-lubricating performance, resistance to ultra-high temperature and chemical reagents, resistance to almost all oils and chemicals. Polytetrafluoroethylene heat shrinkable pipe is widely used in automobile, military industry, aerospace, electronic chemical industry and other fields.
