Abstract

The rubber composition described herein have been found to have an exceptionally long life as a spring-biased actuator diaphragm material that maintains its position compressed, e.g., bolted, between opposed flanges, while maintaining excellent compressibility, low temperature flexibility, hydrocarbon resistance, abrasion resistance and mechanical strength. The compositions include a copolymer rubber component; a plasticizer for the copolymer rubber; a vulcanizing agent for the copolymer rubber; a silica filler; and a coupling agent, such as a silane coupling agent, capable of coupling the silica filler to the copolymer rubber. Ranges may be expressed herein as from ~about~ or ~approximately~ on particular value and/or to ~about~ or ~approximately~ another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value.
