Expanded PTFE

Expanded PTFE (ePTFE) flat gaskets represent the state-of-the-art solution for industrial sealing applications requiring maximum flexibility and absolute chemical resistance. Thanks to a unique multidirectional microporous structure, the material combines the universal chemical inertness of PTFE with exceptional adaptability, ensuring a secure seal even on fragile or irregular flanges.

Expanded PTFE Flat Gasket Cutting

Our specialized expanded PTFE materials are tailored to your most critical applications.

Key advantages of expanded PTFE for flat gasket cutting:

- Maximum flexibility and conformability: the fibrous structure adapts to irregular or fragile surfaces (glass, plastic) with minimal tightening force.
- Excellent creep resistance: drastically reduces cold flow, ensuring a durable seal under high pressure and across a temperature range of -240°C to +270°C.
- Total inertness and purity (pH 0–14): unaffected by aggressive fluids and compliant with FDA and EC No. 1935/2004 standards for the food and pharmaceutical industries.

Available as custom-cut gaskets or in standard formats, our expanded PTFE gaskets ensure reliable sealing performance.
