SBS is mainly used in four fields: rubber products, resin modifiers, adhesives and asphalt modifiers. In terms of rubber products, SBS molded products are mainly used in the shoe (sole) industry, and extruded products are mainly used in hoses and tapes; as a resin modifier, a small amount of SBS blended with polypropylene (PP), polyethylene (PE), and polystyrene (PS) can significantly improve the low-temperature performance and impact strength of the product; as an adhesive, SBS has the characteristics of high solid content, quick drying, and low-temperature resistance; as a modifier for building asphalt and road asphalt, SBS can significantly improve the weather resistance and load resistance of asphalt.
