Custom Expanded PTFE Sheet From China
Expanded PTFE Sheets are made from 100% virgin PTFE resins. Expanded PTFE sheet using a special process that produces a uniform and highly fibrillated microstructure with a great lot of fibers running in multi-direction.
It is 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. It has excellent sealability, cuts easily, and separates cleanly from flanges after use.
