The difference between Teflon tube and glass fiber tube

Have you ever seen the Teflon tube next door fuse temperature is 167 degrees Celsius, if you change to do the glass fiber tube (glass fiber tube is not pure fiberglass, it is other resin lagging synthetic tubing, the general maximum working temperature is 70 ~ 80 degrees Celsius, if it is synthesized with the Teflon tube in order to reach more than 200 degrees), this is the reason why the Teflon tube is able to withstand a maximum of 250 degrees of heat, so it is used here is appropriate
