Expanded PTFE (ePTFE) sheets offer a high-performance sealing solution for demanding applications: chemical, petrochemical, food processing, pharmaceutical, gas treatment, steam, and corrosive fluids. Thanks to their micro-expanded structure, they ensure optimal compression, high resilience, and long-lasting sealing, even on irregular or damaged flanges.
Available formats: standard 1.5 x 1.5 m sheets or custom-cut parts.

ePTFE sheets are manufactured from pure PTFE, expanded to create an aerated structure. This unique architecture allows for controlled deformation, guaranteeing a perfect seal even at low bolt torque.
They are ideal for installations where flanges have defects, irregularities, or significant thermal stresses.
The material is chemically inert, non-contaminating, and compatible with food, pharmaceutical, and ultra-clean environments. The sheets can be cut into standard gaskets (DIN, ANSI, PN) or special shapes according to your requirements.
FAQ – Frequently Asked Questions
Are ePTFE sheets compliant with European PFAS regulations? Yes. Our expanded PTFE sheets are compliant with European requirements regarding per- and polyfluoroalkyl substances (PFAS). They contain no intentionally added PFAS and comply with the regulatory thresholds applicable to industrial sealing materials.
Are they suitable for aggressive chemicals? Yes. Expanded PTFE offers total resistance to acids, bases, and solvents (pH 0 to 14), making it an ideal material for demanding chemical environments.
Can they be used on irregular or damaged flanges? Yes. Their micro-expanded structure ensures high compressibility, allowing for reliable sealing even on imperfect or aged surfaces.
Do you offer custom cutting? Yes. We perform all types of cutting: DIN, ANSI, PN gaskets, special shapes, oval or rectangular gaskets, or based on technical drawings.
