Freudenberg Simrit Simriz® 489 Ultra Pure FFKT Perfluoroelastomer Compound

Perfluoro elastomers – or FFKM for short – have an ideal combination of characteristics, with their excellent chemical resistance, high level of temperature resistance, and high levels of elasticity. Simriz® perfluoro elastomers close the material gap between inelastic PTFE and elastomers, which have poor temperature and chemical resistance properties. With a fluoridation level of 72%, FFKM elastomers have a level of resistance close to that of pure PTFE at 76%. At the same time, FFKM materials are so elastic that they are excellently suited to both static and dynamic seals. Simrit offers ISC O-Rings which are specifically optimised with respect to flexibility at low temperatures, resistance to high temperatures, hardness, tensile strength, elongation, compression set, or color.Information provided by Freudenburg-NOK.
