High-performance expanded PTFE (ePTFE) sealing materials
Ultra-pure microporous ePTFE sheets for demanding industrial sealing. Soft, conformable, and chemically inert — ideal for flat face flanges.
Conformable ePTFE tape for thread sealing and irregular flanges. Resists chemicals, steam, and cryogenic temperatures. No cutting debris.
Custom-cut ePTFE gaskets for any size or shape — round, oval, rectangular, or irregular. Trusted for chemical, pharmaceutical, and food-grade sealing.
Custom parts machined to your exact specifications
Send us your drawings — we machine it for you. Tolerances up to ±0.01mm.
Expert knowledge on PTFE materials, sealing technology, and industrial applications
Standard PTFE (Polytetrafluoroethylene) is known for its chemical resistance, but it suffers from cold flow and creep under load. Expanded PTFE solves these problems with a microporous, fibrillated structure that offers superior conformability, sealability, and zero cold flow.
