evolast® is the next generation of perfluoroelastomers. It combines the exceptional chemical and thermal resistance of PTFE with the elasticity and compression set resistance of elastomers. The result: Seals that withstand extreme temperatures — up to 340°C for premium grades — and a wider range of aggressive chemicals than conventional elastomers.
This makes evolast® the preferred choice for industries requiring high precision, durability, and consistent performance under demanding operating conditions. Key application areas include Chemical Processing, Pharma & Medical, Semiconductors, and Oil & Gas.
evolast® is 100% developed, compounded, and manufactured in-house at our Italian centers of excellence: TSF and MCM High-Performance Sealing. Complete control of the value chain – from material formulation to engineering and production – allows us to offer customized sealing solutions. This ensures short lead times and guarantees European quality and full traceability.
