(57) [Abstract] [Purpose] Low temperature impact resistance, wide coloring freedom, while maintaining the excellent rubber properties over a wide temperature range while taking advantage of the excellent characteristics of styrene elastomer materials. Providing a thermoplastic elastomer that can be used in a wide range of applications including those requiring toning, hygiene, and long-term reliability due to its characteristics such as low residual heavy metals It is to be. [Composition] With respect to 100 parts by weight of the rubber composition (a), 5 to 300 parts by weight of thermoplastic resin (b), SiH in the molecule 0.5 to 30 parts by weight of an organic organosiloxane cross-linking agent (c) having two or more groups, 0.001 to 20 parts by weight of a hydrosilylation catalyst (d), and a compatibilizing agent (e) of 0. A thermoplastic elastomer, which is obtained by mixing 5 to 20 parts by weight and dynamically heat-treating it. |
