| titleOfInvention | Method for producing polypropylene type resin foamed particle |
| abstract | A method for producing polypropylene type resin foamed particles wherein polypropylene type resin particles impregnated with a physical foaming agent and heated together with an aqueous medium and a dispersing agent are released out of a closed vessel to a low pressure region, to produce foamed particles, characterized in that the aqueous medium has an electric conductivity of 0.00 mS/m to 20.00 mS/m. The method can be used for producing good polyolefin resin foamed particles free from the mutual adhesion during its production with almost same amounts, independent of locations of plants for production, of a dispersing agent added for preventing the adhesion of particles in a heat treatment process for impregnating resin particles dispersed in an aqueous medium in a closed vessel with a foaming agent, and of the dispersing agent attached to the resultant foamed articles. The above polyolefin resin foamed particles exhibit good melting and mutual adhesion in a step of forming them and can provide a formed article having excellent mechanical strength, and further can be produced with stability. |
