Thermoplastic Elastomer Composition Having Low Hardness, and Diaphragm Comprising Same |
摘要 |
A thermoplastic elastomer composition of the present invention comprises (A) 30 to 40% by weight of a block terpolymer of an aromatic vinyl compound and alkene or a conjugated diene-based compound; (B) 25 to 50% by weight of a paraffin oil; (C) 1 to 5% by weight of a polyolefin-based resin; (D) 5 to 20% by weight of an inorganic additive; and (E) 5 to 15% by weight of a polyphenylene ether-based resin. The thermoplastic elastomer composition, which has a surface hardness of 0.1 to 40 A (shore A), shows excellent low hardness and has improved physical properties at high temperature, particularly, flexibility, restoring force at high temperatures, and the like. |
