Abstract

Provided is a resin composition which is a material for ink supply tubes and which has excellent moisture barrier performance, air barrier performance, and kink resistance. The resin composition contains a thermoplastic elastomer (A) containing a (b)-(a)-(b)-type isobutylene triblock copolymer containing polymer blocks (a) having isobutylene units and polymer blocks (b) having styrene units and also contains a lubricant (B). The content of the thermoplastic elastomer (A) in the resin composition is 70% to 95% by mass. The content of the lubricant (B) in the resin composition is 5% to 15% by mass. The content of the (b)-(a)-(b)-type isobutylene triblock copolymer in the resin composition is 50% to 95% by mass. The content of the polymer blocks (a) in the (b)-(a)-(b)-type isobutylene triblock copolymer is 80% to 90% by mass. The content of the polymer blocks (b) in the (b)-(a)-(b)-type isobutylene triblock copolymer is 10% to 20% by mass.
