Soft EPTFE Expanded PTFE Sheet Gasket Tape with Thickness 0.5mm-10mm
PTFE has good corrosion resistance, wear resistance and high temperature resistance, and is suitable for various chemical media, petroleum, gas and other industries.
The material of expanded PTFE gaskets is pure PTFE resin particles. The PTFE resin particles are heated and compressed through a certain process to form expanded PTFE gaskets. Body PTFE gasket.Ordinary PTFE is a sheet material made by melting at high temperature.
- The material difference between expanded PTFE gaskets and ordinary PTFE.

- The difference between the application fields of expanded PTFE gaskets and ordinary PTFE.
Ordinary PTFE is mainly used in valves, pumps, seals, sliding bearings and other fields.Due to its high elasticity, low compression deformation rate and good air tightness,
expanded PTFE gaskets are widely used in valves, pumps, heat exchange equipment, reactors and pipelines under harsh conditions such as high temperature and high pressure. sealing work.
- Differences in performance characteristics between expanded PTFE gaskets and ordinary PTFE
- . Expanded PTFE gaskets have better expansion properties and can fill gaps with very little pressure to achieve a good sealing effect.
- . Expanded PTFE gasket has good elasticity and good adaptive ability, and can still maintain good sealing performance in environments with high temperature, high pressure, and large changes in shear force.
- Expanded PTFE gasket has a low compression deformation rate and is more suitable for maintaining a sealed state for a longer period of time.
- Ordinary PTFE has good corrosion resistance, wear resistance and high temperature resistance, and is suitable for various chemical media, petroleum, gas and other industries.
To sum up, there are obvious differences between expanded PTFE gaskets and ordinary PTFE in terms of materials, application fields and performance characteristics, and they need to be selected according to the actual situation.If it needs to be used in extreme environments such as high temperature and high pressure, expanded PTFE gaskets are usually a better choice.
