摘要：
The present invention aims to provide a dynamically-crosslinked thermoplastic elastomer composition that can provide a molded product exhibiting low compression set especially in the case of being cooled under stress. The present invention relates to a thermoplastic elastomer composition, including a dynamically-crosslinked butyl rubber and a thermoplastic resin; and having a thermoplastic resin content of not more than 8% by mass. The dynamically-crosslinked butyl rubber is preferably a halogen-containing butyl rubber.
