Elastomer for compression seals.* explosive decompression Explosive decompression (ED) refers to a sudden marked drop in the pressure of a system that occurs in less than 0.1 seconds, associated with explosive violence. Generally it results from some sort of material fatigue or engineering failure, causing a contained system to resistance * low temperature, chemical resistance Explosive decompression often occurs when high-pressure gas molecules migrate into an elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. seal at a compressed state. When the pressure surrounding the seal is released suddenly, the compressed gas inside the elastomer tries to expand and escape, causing damaging tears, blisters and cracks. Specially designed for explosion decompression resistance, FKM FKM Fluoroelastomer FKM Fogarty Klein Monroe (Houston, Texas) FKM Field Kitchen, Modular 935 fluorocarbon fluorocarbon /flu·o·ro·car·bon/ (floor´o-kahr?b?n) any of the class of organic compounds consisting of carbon and fluorine only. elastomer offers chemical resistance to methanol, sour gas Sour gas is natural gas or any other gas mixture which contains significant amounts of hydrogen sulfide (H2S). According to this reference [1], natural gas is usually considered sour if there are more than 5. up to 20%, steam and corrosion inhibitors, as well as lower temperature resistance down to 35[degrees]F. This material is available as O-rings, GT rings, and other custom-molded shapes. These seals can prevent equipment failures from unexpected pressure drops in compressor components, valves and pumps used in such hostile-environment applications as hydrocarbon refining, pipeline and oilfield industries.
