What is difference between F4 tube and teflon pipe?

f4 tube
F4 pipe and teflon lined tubing is the same thing and its material molecular formula is composed of 4 fluorine atoms and 2 carbon atoms.

This material was developed by DuPont in 1938. Then DuPont registered its trademark as Teflon. In the 1960s and 1970s, this material was introduced into China in large quantities.
F4 tube can also be called PTFE pipe, Teflon pipe, F4 pipe. Because of its excellent characteristics, it is commonly known as the "King of Plastics".
Flexible teflon tubing characteristics:
1,Non adhesion:
Teflon sleeving does not adhere to other substances. Even if there is some adhesion, it can be removed with a simple method. It is waterproof, oil proof, dirt proof and easy to clean.

2,High temperature resistance:Ptfe tub has excellent high temperature resistance. The maximum temperature resistance can reach 260 ℃. Its low temperature resistance can reach - 70 ℃.

3. Corrosion resistance:
Ptfe teflon hose are known as "King of Plastics". They are not react to almost all chemicals or solvents. It can react with fluorine and alkali only at high temperature.

4. Abrasion resistance:
Rigid teflon tubing has extremely low friction coefficient and excellent wear resistance. It shows excellent wear resistance even in bearing heavy load sliding.
