Expanded PTFE sheet is an extremely compressible material manufactured from 100%
virgin PTFE. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries.
The material is commonly converted into gaskets and is a popular option with delicate, worn and damaged flanges as it has a low bolt load requirement. It can also withstand compressive loads of over 40,000 psi without losing any sealing capability.
