FFKM-SIMRIZ®
Simriz® is a range of O-rings in perfluoroelastomer (FFKM) compounds by Freudenberg Sealing Technologies, offering exceptional chemical compatibility and heat resistance. Designed for industries like chemical processing, oil and gas, aerospace, and semiconductors, it stands out with its broad chemical stability, like PTFE, combined with the rubbery-elastic qualities of an elastomer. Simriz® seals withstand extreme temperatures (up to 325°C) and harsh chemicals, making them ideal for demanding environments.
The FFKM Chemical Compatibility can be reviewed in our Chemical Resistance Guide.

Simriz® is a premium range of perfluoroelastomer (FFKM) compounds developed by Freudenberg Sealing Technologies, offering exceptional chemical resistance, thermal stability, and elasticity. These seals are designed to meet the stringent demands of industries such as chemical processing, oil and gas, aerospace, semiconductors, and pharmaceuticals. Simriz® compounds exhibit chemical resistance comparable to PTFE (polytetrafluoroethylene), making them suitable for aggressive environments involving acids, bases, oxidizers, and solvents.
Simriz® seals are widely used across multiple industries due to their robust performance. In chemical processing, they withstand harsh chemicals and extreme temperatures in reactors and pipelines. In the oil and gas sector, they perform reliably under high-pressure environments and resist rapid gas decompression (RGD). For semiconductors, high-purity compounds like Simriz® 489 ensure compatibility in plasma applications. In pharmaceuticals, they provide purity and compliance for drug manufacturing processes. Additionally, in aerospace, they ensure durability in high-temperature and chemically aggressive conditions.
Freudenberg's vertical integration allows them to manufacture Simriz® seals from monomers to finished products, ensuring cost efficiency and quality control. This integration also enables them to offer quick tooling for custom sizes within weeks, catering to unique customer requirements. Overall, Simriz® seals represent a cutting-edge solution for demanding environments where conventional elastomers fail, combining chemical resistance, thermal stability, and elasticity to meet critical application needs.
