EPTFE Gasket Sheet
EPTFE Gasket Sheet is a form of PTFE which is expanded and stretched in many different directions during the manufacturing process. This multi-directional, higher strength material demonstrates a reduced tendency to creep under load at elevated temperatures when ompared with other PTFE gasket materials. EPTFE gasket sheet shows good mechanical recovery over long term compression and temperature fluctuation resulting in very low leakage rates and, due to the very soft texture of the material, conforms perfectly to pitted, uneven flange faces.

Frequently Asked Questions – EPTFE Gasket Sheet
What is the difference between EPTFE and standard PTFE gasket sheet?
EPTFE (expanded PTFE) is produced through a multi‑directional expansion process that creates a micro‑porous, fibrous structure. This gives it superior conformability, higher compressibility, and better creep resistance compared to standard PTFE, making it ideal for sealing imperfect flanges and low‑bolt‑load applications.
Is EPTFE gasket sheet suitable for food and pharmaceutical applications?
Yes, our EPTFE gasket sheet complies with FDA 21 CFR 177.1550 and USP Class VI, making it safe for food, beverage, and pharmaceutical contact applications.
What thicknesses and sizes are available?
Standard thicknesses range from 0.5 mm to 6.0 mm, with sheet sizes up to 1500×1500 mm. Custom thicknesses and dimensions are available upon request.
Can EPTFE gasket sheet seal damaged or pitted flanges?
Absolutely. The soft, highly conformable nature of EPTFE allows it to flow into surface imperfections, providing a reliable seal even on pitted, scratched, or uneven flange faces.
What is the maximum temperature for EPTFE gasket sheet?
EPTFE gasket sheet can operate continuously from -200°C to +260°C, making it suitable for both cryogenic and high‑temperature services.
