POLYPROPYLENE-BASED RESIN FOAM PARTICLE, AND FOAM PARTICLE MOLDING

摘要

To provide polypropylene-based resin foam particles which enable production of a foam particle molding having good appearance and excellent mechanical physical properties such as compression strength in a wide molding heating temperature range; and polypropylene-based resin foam particles which enable production of a foam particle molding having a desired shape and good appearance even by omitting a cure step.SOLUTION: There is provided a foam particle molding in which cylindrical polypropylene-based resin foam particles having a through hole and foam particles are mutually fused to each other. An average pore diameter d of the foam particles is within a specific range, and a ratio d/D of the average pore diameter d to an average outer diameter D is within a specific range. A polypropylene-based resin constituting the foam particles is an ethylene-propylene-butene copolymer, a butene component content and an ethylene component content are specific amounts, and bending elastic modulus of the polypropylene-based resin is within a specific range.SELECTED DRAWING: None
