1. High temperature resistance. Teflon heat shrinkable tube has excellent heat resistance, the continuous working temperature can reach 260 ℃, and the working temperature can be withstood in a short time is 300 ℃. Its thermal stability is obvious, and there will be no melting at high temperature.

2. Low temperature resistance. Its mechanical toughness and low temperature resistance are also particularly outstanding, and embrittlement does not occur even in an ultra-low -65°C environment.

3. Corrosion resistance. Its chemical properties are relatively stable, is an inert material, for some strong acid, alkali and a variety of organic solvent reaction is not obvious, can be used as a protective layer of equipment parts, to promote its better protection from chemical corrosion.

4, weather resistance. Even if the Teflon heat shrinkable tube is exposed to the atmosphere for a long time, its surface and material properties are not easy to change, and it is not easy to aging.

Teflon spraying is only harmful to the human body after reaching a certain temperature decomposition. The non-stick PTFE spray will not change in the temperature range from normal temperature to 260°C. The temperature used in daily cooking is usually only about 200 ℃, and even if frying is used, the oil temperature will generally not exceed 250 ℃. Therefore, in normal cooking, there is no need to worry about the decomposition of the coating to release harmful substances.
