NOVELTY - Preparation of high-efficiency supercritical molded foamed elastomer involves (1) using thermoplastic elastomer as the base elastomer, adding other types of elastomers as performance supplements, (2) mixing the elastomer particles in step (1) with a lubricant, a foaming agent, a crosslinking agent, and a nucleating agent to prepare a composite board by mixing, smelting, and molding, and (3) foaming the composite board obtained in step (2) using a supercritical compression molding method. USE - Preparation of high-efficiency supercritical molded foamed elastomer. ADVANTAGE - The method is simple, the content of formamide after foaming is 0, and the whole process is environmentally friendly and highly efficient.
