Title:
POLYOLEFIN RESIN PARTICLES AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/179786
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing novel polyolefin resin particles that enable provision of foamed particles with which it is possible to provide a molded article having excellent surface properties. Said problem is achieved by polyolefin resin particles that contain a polyolefin resin as a base resin, that have a particle weight within a specific range, and that has an L12/D12 shrinkage rate of 50% or more. Formula (1): L12/D12 shrinkage rate = 100 × (1-(average L2/D2 ratio of foamed particles) / (average L1/D1 ratio of resin particles))
