RELAY BLOCK

摘要

A relay block that has inhibited the occurrence of casting cockles and has remarkably inhibited the deformation of thin portions. In particular, a relay block produced by molding a resin composition comprising a block copolymer comprising a polymer block composed mainly of a polyamide, a polyphenylene ether and at least one aromatic vinyl compound and a polymer block composed mainly of at least one conjugated diene compound, the resin composition exhibiting an MVR of 60 cm<3>/10 min or greater and a dimensional change ratio at water absorption of 1.0% or less.
