Superior Thermal and Chemical Resistance
FFKM O-Rings
Superior Thermal and Chemical Resistance
Simriz® perfluoroelastomers offer high-end solutions in materials technology. In terms of its resistance to media and temperature, Simriz is suited to the most demanding applications.
Through the use of perfluorinated, completely hydrogen free monomers, combined with the appropriate compounding and processing technologies, it is possible to produce materials with rubbery-elastic qualities and a high media and temperature resistance.
Simriz stands out for its broad chemical stability, similar to that of PTFE, combined with the rubbery-elastic qualities of an elastomer. They are used wherever extreme safety standards are in force and high maintenance and repair expenditures exceed the costs of the seals.
| Material Code | Description | Tensile Strength | Elongation | Compression Set | Temperature | Data Sheet |
| SZ481 | Simriz® 481 performs well in a wide variety of harsh chemicals. Its outstanding low temperature performance makes the Simriz® 481 the perfect match for nearly every application in the chemical process industry, especially where low temperatures are expected. | 2480 psi | 260% | 27% | -30°C to +230°C |  |
| SZ498 | Simriz® 498 is the ultimate FFKM material. Its unique patented material structure provides outstanding long-term performance in nearly every environment. No matter if it’s extreme temperatures up to 325°C or harsh chemicals or even overheated steam and hot water. Simriz® 498 is the best match. | 2700 psi | 160% | 12% | -6°C to +325°C | |
| SZ134 | Simriz® 134 performs well in a wide variety of harsh chemicals. Its outstanding resistance against rapid gas decompression (RGD) makes Simriz® 134 the perfect match for high-pressure gas applications. | 3118 psi | 160% | 23% | -15°C to +230°C | |
