| Material: | PTFE |
| Backing Type | Hard (this valve seat cannot be replaceable) |
| Available Size | DN50-1200 |
| Suitable Working Medium: | Corrosive chemicals |
PTFE is the common soft-seal seat material of valve products, also called "Plastic King".
It is a polymer compound formed by polymerization of tetrafluoroethylene, which has good chemical stability.
Applicable temperature of PTFE can be -40℃ ~ 200℃.
1. Good chemical stability.
2.PTFE is resistant to all chemicals, except molten sodium metal and liquid fluorine.
3. It is widely used in various media that need resistance to acids, alkalis and organic solvents.
