SEBS based on partially saturated block copolymers consisting of the rigid polystyrene phase and the soft ethylene/propylene phase, resulting from the hydrogenation of unsaturated bonds. The presence of hard polystyrene domains in the elastomer matrix provides physical cross- linking products with SEBS. The compounds have excellent flexibility, are easy to process and coloration. Fully saturated character of flexible phase, makes SEBS is resistant to weathering, ozone and UV, makes also wider range of usage temperatures and the ability to use higher processing temperature. Application: more demanding products in automotive and construction industries. Hoses and cables. Multi- component overmolding for technical products, medical , household, sport equipments and many others.
