Expanded PTFE Products

High-performance expanded PTFE (ePTFE) sealing materials โ€” soft, microporous, and chemically inert, our expanded PTFE products eliminate cold flow and deliver superior sealing performance in demanding industrial applications.

Expanded PTFE Sheet

Expanded PTFE Sheet

Our expanded PTFE sheet (ePTFE sheet) is a microporous, fibrillated material offering zero cold flow, superior conformability, and outstanding chemical resistance. This expanded PTFE sheet is the preferred choice for demanding flat face flange sealing in chemical, pharmaceutical, and food-processing applications.

  • Temperature: -240ยฐC to +260ยฐC
  • Max Size: 1520ร—1520mm
  • Thickness: 0.5mm ~ 13mm

Expanded PTFE Tape

Expanded PTFE Tape

Our expanded PTFE tape (ePTFE tape) is a highly conformable expanded PTFE material ideal for thread sealing and irregular flange surfaces. This expanded PTFE tape resists virtually all chemicals, steam, and cryogenic temperatures โ€” with no cutting debris, making it cleaner to apply than traditional PTFE tape.

  • Width: 12 / 20 / 30 / 50mm
  • Thickness: 3mm ~ 8mm
  • Roll Length: 5m / 10m / 15m

Expanded PTFE Gasket

Expanded PTFE Gasket

Custom-cut expanded PTFE gaskets (ePTFE gaskets) available in any size or shape โ€” round, oval, rectangular, or fully custom. Our expanded PTFE gaskets are trusted for chemical, pharmaceutical, and food-grade sealing applications where superior conformability and zero cold flow are essential.

  • Shapes: Any shape available
  • FDA & USP Class VI compliant
  • Custom dimensions per drawing

PTFE Insights

Expert knowledge on PTFE materials, sealing technology, and industrial applications

What Is Expanded PTFE (ePTFE)?

What Is Expanded PTFE (ePTFE) and Why Is It Different from Regular PTFE?

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.

How to Choose the Right PTFE Seal

How to Choose Between PTFE Sheet, Gasket, and Tape for Your Flange

PTFE sheet gasket, pre-cut gasket, or joint sealant tape? The right choice depends on your flange type, pressure rating, temperature, and whether the flange is standard or custom geometry. Learn the key decision criteria that help engineers select the right ePTFE sealing product every time.
