Title: FOAM PARTICLES AND FOAM PARTICLE MOLDED BODY
Abstract:
The present invention provides foam particles of a block copolymer that is composed of a polyethylene block and an ethylene/α-olefin copolymer block. The foam particles have excellent in-mold moldability and are configured such that: the xylene-insoluble fraction (A) as determined by a hot xylene extraction method is 10-70% by weight; and the ratio of the xylene-insoluble fraction (A) to the xylene-insoluble fraction (B) as determined by a hot xylene extraction method, while dividing the foam particles into two halves, namely the ratio (A)/(B) is 1.0-1.1. The present invention also provides a foam particle molded body which has excellent fusibility and recoverability.
