  • PLANT-DERIVED POLYAMIDE-BASED ELASTOMER FOAM MOLDED BODY, METHOD FOR MANUFACTURING SAME, AND FOAM PARTICLES THEREOF
    Publication number: 20220153949
    Abstract: Since most elastomer foam molded bodies use a petroleum-derived resin as a base resin, there is a demand for an elastomer foam molded body with high rebound resilience and low environmental load. An object of the present invention is to provide a foam molded body having a rebound resilience coefficient equivalent to that of a petroleum-derived polyamide-based elastomer foam molded body, and excellent moldability during in-mold foaming; foam particles; and a method for producing the foam molded body. The present invention relates to a polyamide-based elastomer foam molded body comprising 50 to 100 mass % of a block copolymer resin containing a polyamide block as a hard segment and a polyether block as a soft segment, wherein the copolymer resin has a biobased product content as measured by ASTM D6866 of 30% or more.
