COG introduces a new range of FFKM materials developed to be resistant to temperature, vapour and solvents: COG Resist®. The FFKM product family features three compounds: two universal materials and a special FFKM compound to be used in the oil and gas industry. The two all-round materials, COG Resist® RS 75 AL and COG Resist ® RS 80 AL, demonstrate outstanding resistance to chemicals and acids, as well as possessing excellent 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 extremely low levels of swelling.
The COG Resist® RS 92 AED seal material was developed especially 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 you need. The compound combines extraordinary chemical resistance with excellent thermal resistance. These properties, along with its low compression set, mean that it is especially suitable for meeting the high demands made by the oil and gas industry in particular, for example, for use in deep sea valves, pumps or compressors.
The material properties that the COG Resist® FFKM seals demonstrate enable a longer service life in an extremely wide range of demanding industrial applications.
