PURPOSE:A low-resilience rubber foam suitable as a shoe material capable of absorbing a strong impact resulting from walking or running, prepared by adding a filler, a plasticizer, a blowing agent, and a vulcanizing agent to a specified rubber mixture and expanding and curing the mixture by heating. CONSTITUTION:A low-resilience rubber foam having a resilience of 0-35%, obtained by mixing 100pts.wt. high-styrene content styrene-butadiene copolymer/ general-purpose rubber mixture comprising a high-styrene content styrene-butadiene copolymer of a styrene content controlled at 53-75wt% during polymerization or by blending and 40wt% or below, based on the total mixed rubber weight, general-purpose rubber with 30-300pts.wt. filler, 5-60pts.wt. plasticizer, 0.5-50pts.wt. blowing agent, and a vulcanizing agent and expanding and curing the resulting mixture by heating. This foam is suitable as a shoe material capable of absorbing a strong impact resulting from walking or running and of protecting the nervous system or joint system of food. |
