Rubber material null for ultralow hardness vibration proof

摘要

PROBLEM TO BE SOLVED: To obtain a rubber vibration isolating material for isolators of acoustic equipments, computer related equipments, game machines or the like and having low hardness, small permanent compression set, large dissipation factor and small temperature dependence.;SOLUTION: This rubber material is obtained by crosslinkingly curing a rubber composition characterized by including 50-200 pts.wt. extender constituent per 100 pts.wt. partially crosslinked isobutylene-isoprene rubber.;COPYRIGHT: (C)2000,JPO
