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.
