PTFE(F4) |
1.a kind of plastic with the most stable chemical properties. It can withstand boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as strong alkali and various organic solvents. Not resistant to corrosion by chlorine trifluoride, high temperature chlorine trifluoride, high-speed liquid fluorine, liquid oxygen, and ozone. 2. Wear resistance not as good as polyurethane 3. The resistance to negative pressure not as good as polychloroprene. |
70℃ |
100℃ 120℃(Special) |
1.Strong corrosive fluids such as concentrated acid and alkali 2. Sanitary fluids |
FEP(F46) |
The chemical resistance of FEP is similar to that of PTFE, and it has excellent chemical resistance. |
100℃ 120℃ (Speacial) |
Same as above |
|
PFA |
The chemical resistance of PFA is similar to that of PTFE, and it has excellent chemical resistance, but its creep resistance and compressive strength are better than PTFE, and its tensile strength is higher. |
100℃ 150℃ (Speacial) |
Same as above |
|
Polychloroprene |
1. Excellent elasticity, high breaking force, good wear resistance 2. Resistance to corrosion of acid, alkali and salt with low concentration, and not to corrosion of oxidizing fluids |
