Abstract: Provided is a method for producing expanded polypropylene resin particles that can be used as a material for an in-mold expanded molded product which maintains an inherent strength of a base resin despite a high expansion ratio. The method for producing expanded polypropylene resin particles includes producing first-step expanded particles which have a low percentage of wrinkle-induced shrinkage as low as 5% or less, from polypropylene resin particles made of a polypropylene resin composition containing a specific polyethylene resin.

Abstract: A process for producing expanded polyolefin resin particles with use as a foaming agent of water contained in an aqueous dispersion medium. The process includes dispersing polyolefin resin particles together with the aqueous dispersion medium into a closed vessel; heating the polyolefin resin particles up to or above a softening temperature of the polyolefin resin particles and pressurizing the polyolefin resin particles; and releasing the polyolefin resin particles into a zone whose pressure is lower than an internal pressure of the closed vessel. The polyolefin resin particles are composed of a polyolefin resin composition including polyolefin resin, polyvalent alcohol and a foam nucleating agent.

Abstract: Foamed polypropylene-resin particles are obtained by dispersing polypropylene-resin particles containing polyethylene glycol and/or glycerin together with an aqueous dispersion medium in a pressure-resistant container; introducing carbon dioxide gas as a foaming agent into the pressure-resistant container; impregnating the polypropylene-resin particles with the foaming agent under a heating and pressure condition; and then discharging the polypropylene-resin particles into an area having a lower pressure than an internal pressure of the pressure-resistant container and having an atmosphere temperature of higher than 80° C. and not higher than 110° C. The foamed polypropylene-resin particles can yield an in-mold foam molded body at a low heated water vapor pressure for molding, do not lose moldability at a high heated water vapor pressure for molding, have a wide heated water vapor range for molding, exhibit good moldability even when a mold with a complicated shape, a large mold, or a similar mold is used.
