Expanded ePTFE Sheet

Expanded PTFE is made by stretching extruded PTFE paste biaxially under controlled heat, creating a microporous, node-fibril structure that blocks liquids but allows vapor to pass. This expanded ptfe sheet compresses evenly for reliable sealing in flange gaskets under chemical exposure and temperature cycles from -40°C to 120°C. As a direct expanded ptfe supplier, we stock rolls in 0.5–10 mm thickness and up to 1800 mm width, ready for fast delivery and custom cutting.For cable insulation in offshore wind farms, we supply wider sheets that wrap tightly around bundles, reducing weight by 30 % compared to solid PTFE while still blocking salt spray and UV damage.
