A foam and flame-breakable resin composition comprising a non-inflammable agent, an auxiliary non-inflammable agent, a foaming agent, an ash coagulating agent and a resin system consisting essentially of a blend of a copolymer of ethylene and vinyl acetate having a high melt viscosity with the vinyl acetate content being between 40 to 80 weight percent and the molecular weight being more than 200,000, and polyvinyl chloride in a ratio of copolymer to polyvinyl chloride of 2:8 to 7:3. The composition may be further subjected to vulcanization treatment. |
