Abstract
There is provided an elastomer composition having both of a flexibility and a wear resistance at a low temperature, while having a high conductivity, and containing an elastomer component (A) including styrene-based thermoplastic elastomer (a1) and propylene-based elastomer (a2); and containing 10 pts.mass or more and 100 pts.mass or less of a conductivity imparting agent (B), and 10 pts.mass or more and 300 pts.mass of less of a process oil (C) based on 100 pts.mass of the elastomer component (A).
Claims19
An elastomer composition, comprising:
- an elastomer component (A) consisting of styrene-based thermoplastic elastomer (a1) and propylene-based elastomer (a2);
- a conductivity imparting agent (B) contained in an amount of 10 pts.mass or more and 100 pts.mass or less based on 100 pts.mass of the elastomer component (A);
- and
- a process oil (C) contained in an amount of 10 pts.mass or more and 300 pts.mass or less based on 100 pts.mass of the elastomer component (A),
- wherein only the elastomer component (A) is contained as a polymer component, and
- wherein the styrene-based thermoplastic elastomer (a1) consists of a styrene-ethylene-ethylene-propylene-styrene block copolymer.
A molded article composed of an elastomer composition, the elastomer composition comprising:
- an elastomer component (A) consisting of styrene-based thermoplastic elastomer (a1) and propylene-based elastomer (a2);
- a conductivity imparting agent (B) contained in an amount of 10 pts.mass or more and 100 pts.mass or less based on 100 pts.mass of the elastomer component (A);
- and
- a process oil (C) contained in an amount of 10 pts.mass or more and 300 pts.mass or less based on 100 pts.mass of the elastomer component (A),
- wherein only the elastomer component (A) is contained as a polymer component, and
- wherein the stryene-based thermoplastic elastomer (a1) consists of a styrene-ethylene-ethylene-propylene-styrene block copolymer.
