evolast® Perfluorinated rubber – FFKM

FFKM materials are elastomers ­offering the highest chemical and heat ­resistance. Some FFKM types can be ­exposed to temperatures over 300°C. The resistance to chemicals is ­nearly ­universal and ­comparable to that of PTFE.

evolast® parts, the ultimate ­generation of perfluoroelastomers (FFKM according to ASTM D1418), are designed to combine the needs for chemical and thermal resistance provided by PTFE with the sealing properties (compression set) typical of elastomers.

evolast® seals are used in heavy duty equipment in critical processes where mechanical seals, valves, pumps, require the maximum of performance in particularly harsh environments.

evolast® items are available in the usual shapes such as O-rings and gaskets both in standard and ­customized dimension.

evolast® parts are recommended for extremely severe applications where difficult and costly maintenance strongly reqiures reduced process downtimes.

Thanks to a wide range of specific FFKM grades and compounding ­recipes, evolast® components ­have outstanding properties well above any other elastomers including FKM and FEPM.

Oustanding resistance in ­aggressive chemicals, acids, ­organic and inorganic media, ketones, esters, solvents, amines, hot steam and water.

Wide range of temperatures from -25°C up to 270°C for ­standard ­grades, up to and 340°C for ­premium grades. Special grades from -40°C up to 260°C are also available.
