Abstract

CapStymer SEBS is the strongest, the most highly dilutive, and the most compatible with polyolefins and mineral oils of all the styrenic thermoplastic block copolymers. CapStymer SEBS polymers are second generation styrenic block copolymers with a hydrogenated midblock of styrene-ethylene/butylene-styrene (SEBS). They are intended for use where UV resistance, high service temperature, and processing stability are essential.

CapStymer SEBS polymers are the material of choice for production of soft, strong compounds for handles and grips, elastic components in diapers, oil gels for telecommunications and medical applications, impact modifiers of engineering thermoplastics, flexibilizers/tougheners for clear polypropylene.

Applications

1. TPE compound

TPE of A0-95 shore can be produced through mixing CapStymer SEBS with polypropylene, naphthene oil, hydrogenated naphthene oil, white oil etc. Such elastomers have excellent surface quality, weather fastness and aging resistance. It is extensively used for soft material such as handles, stationery, toys, handgrips of sports equipment, sealing strip, wires and cables, toothbrush stem and other wrap material.
