PURPOSE:To improve vibration-damping properties and elongation by compounding a mixture contg. a rubber component comprising natural or chloroprene rubber, a specific nylon fiber, and a carboxylated acrylonitrile-butadiene rubber with a filler and vulcanizing the resulting rubber compsn. CONSTITUTION:A mixture contg. 100wt.% rubber component comprising natural or chloroprene rubber, 5-30wt.% nylon fiber having a mean diameter of about 0.2mum or higher and a length of about 1mm and grafted with natural rubber, and 5-30wt.% carboxylated acrylonitrile-butadiene rubber pref. in the form of liq. is compounded with a filler and, if necessary, a plasticizer, a process oil. etc., to give a rubber compsn., which is vulcanized to give the title material. |
