Expanded PTFE Sheets are made from 100% virgin PTFE resins. A special process produces a uniform and highly fibrillated microstructure with many fibers running in multiple directions.
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. It also has excellent sealability, cuts easily, and separates cleanly from flanges after use.

An expanded PTFE sheet is a versatile material used in many industries due to its exceptional durability and resistance to harsh environments. It is widely used for expanded PTFE gaskets and is a good choice for fragile, worn, and damaged flanges. It can also sustain compressive stresses of up to 40,000 pounds per square inch without compromising its sealing capacity.
