ePTFE sheet gaskets for sealing

Expanded PTFE Sheet

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.

Feature

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. expanded PTFE sheet can also sustain compressive stresses of up to 40,000 pounds per square inch without compromising its sealing capacity.

Feature:

  1. Excellent resistance to creep and cold flow
  2. The clean and soft sealing material, harmless in contact with food
  3. Easy to install, easy to cut, punch and plot
  4. Excellent recovery properties; suitable for changing loads
  5. Suitable for high-temperature applications
  6. Allows a precise mathematical approach to the sealing application
