The FFKM product family COG Resist launches four compounds: two universal materials, a special FFKM compound for use in the oil and gas industry and a compound for the food and pharmaceutical industry. The two all-round materials, COG Resist RS 75 AL and COG Resist RS 80 AL demonstrate resistance to chemicals and acids, as well as mechanical properties. COG Resist RS 75 AL is therefore heat resistant at temperatures of up to +325 °C, and COG Resist RS 80 AL is heat resistant up to +260 °C. And what’s more, both FFKM compounds demonstrate low gas permeability and low levels of swelling.
The COG Resist RS 92 AED seal material was developed for applications where resistance to explosive decompression is required, and has been tested to Norsok standard M-710 and NACE TM 0297. Wherever seal materials are exposed to high pressure and aggressive media, COG Resist RS 92 AED provides the security needed. The compound combines chemical resistance with thermal resistance. COG Resist RS 75 HS can be used with the high demands of food, medicine and pharmaceutical industries. It has resistance to CIP and SIP procedures and is free from animal-derived ingredients (ADI free). It has the approvals for USP Class VI up to +121 °C, FDA 21. CFR 177.2400 and CFR 177.2600 as well as 3-A Sanitary Standard.
