Abstract
Disclosed herein is a composition for a gasket, including about 100 parts by weight of a hydrogenated styrene-based block copolymer, about 70 to 99 parts by weight of a petroleum-based softener, about 10 to 25 parts by weight of a polyolefin-based resin; about 10 to 25 parts by weight of an inorganic filler, and about 10 to 25 parts by weight of a heat-resistant polymer, based on 100 parts by weight of the hydrogenated styrene-based block copolymer. The thermoplastic elastomer composition has superior physical properties, such as tensile strength, heat resistance, high-temperature restoring force and chemical resistance, while being applicable to injection-molding and recyclable, like general thermoplastic resins. Disclosed herein is further a gasket produced from the composition.

A washing machine comprising:
- a body;
- a tub provided in the body;
- a drum provided in the tub, the drum being rotatable and being provided with an opening for receiving laundry;
- a door provided at a front of the body;
- and
- a gasket including a first annular section configured to engage with a rim of the tub, a second annular section configured to engage with the body and a vibration absorbing section disposed between the first annular section and the second annular section to reduce transfer of vibration from the tub to the front of the body,
- wherein the gasket is manufactured by a plastic injection molding process using a plastic mold, the plastic injection molding process using plastic as a base material mixed with additives such that the manufactured gasket has a hardness of 30 to 50 in accordance with KS M 6518.
