Japan, Sept. 18 -- JSP CORP has got intellectual property rights for 'PRODUCTION METHOD OF FOAMED PARTICLE, AND RESIN RAW MATERIAL FOR FOAMED PARTICLE.' Other related details are as follows:
Application Number: JP,2022-162720
Category (FI): C08J9/18
Stage: PROBLEM TO BE SOLVED: To provide a production method of foamed particles which can effectively utilize a resin component derived from a member for an automobile, and can produce foamed particles having good in-mold moldability, and a resin raw material used in the production method of the foamed particles.SOLUTION: A production method of foamed particles foams resin particles composed of a polypropylene-based resin composition by a direct foaming method. The resin particles are composed of a molten mixture of a polypropylene-based resin composition A which contains a polypropylene-based resin composition a derived from a member for an automobile and has a melting point of 160degC or higher, and a polypropylene-based resin B having a melting point of 130degC or higher and lower than 160degC. A mass ratio of the polypropylene-based resin composition A to the polypropylene-based resin B in the resin particles is 3:97 to 60:40.SELECTED DRAWING: Figure 2 (Grant)
