  • POLYAMIDE-BASED RESIN PRE-EXPANDED PARTICLES, POLYAMIDE-BASED RESIN FOAM SHAPED PRODUCT, AND METHOD OF PRODUCING POLYAMIDE-BASED RESIN FOAM SHAPED PRODUCT
    Publication number: 20220169849
    Abstract: The present disclosure is directed to provide polyamide-based resin pre-expanded particles which can serve as a raw material of a polyamide-based resin foam shaped product having an excellent mechanical strength. Polyamide-based resin pre-expanded particles of the present disclosure contain a polyamide-based resin. The polyamide-based resin pre-expanded particles have an expansion ratio of 1.0 or more, wherein the expansion ratio is a ratio (?1/?2) of a density ?1 (g/cm3) to a density ?2 (g/cm3) after being pressurized with air at 0.9 MPa and then heated for 30 seconds with saturated steam at a temperature higher than a thermal fusion temperature by 5° C.
