IMPACT-ABSORBENT GELL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an impact-absorbent gell material which has a reduced surface stickiness and an improved weatherability while maintaining its high damping capacity. SOLUTION: This gel material is obtd. by cross-linking a compsn. obtd. by compounding a polymer component comprising 30-70wt.% ethylene-α-olefin rubber and 70-30wt.% styrene-vinylisoprene-styrene copolymer having a styrene unit content of 30% or lower with a softener and a peroxide as the cross-linker.
