Abstract: Disclosed herein are various cable gel seal arrangements and thermoplastic gels useful therein. The thermoplastic gels are prepared from a composition including a styrene triblock copolymer, a styrene diblock copolymer, an oil extender, and an additive selected from poly(2,6-dimethyl-1,4-phenylene oxide), a C9 resin, poly(alpha-methylstyrene), a coumarone-indene resin, and combinations thereof, wherein the additive has a Tg from about 95° C. to about 200° C. The thermoplastic gels advantageously exhibit low compression set.

Abstract: A rubber composition capable of manufacturing a sheet transport roller having an excellent friction coefficient and wear resistance. A sheet transport roller rubber composition contains an ethylene-α-olefin-diene copolymer as a base rubber, a sulfur-based crosslinking agent, and a coumarone-indene resin. It is preferable that the sheet transport roller rubber composition be obtained by mixing the base rubber and the coumarone-indene resin at a temperature equal to or higher than a softening point of the coumarone-indene resin to prepare a mixture, and then mixing this mixture with a sulfur-based crosslinking agent.
