FFKM - SIMRIZ® – Perfluoroelastomer
With Simriz® perfluorelastomers, Freudenberg Sealing Technologies is offering the processing industry the high-end solution 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.
The corresponding requirements are found in the chemical sector as well as the oil production and processing industries, appliance and vehicle manufacturing, and the aerospace industry. The special compounds Simriz 491 and Simriz 495 are available for those applications. Besides Simriz compounds for standard and high-temperature applications, versions with FDA¹ and USP Class VI² certifications like Simriz 494 and Simriz 506 are available. They are designed to be ideal for use in food and pharmaceutical production.
