Hydrogenated styrenic block copolymers(HSBCs)provide excellent weather resistance and lower odour risks compared with un-saturated SBS or SIS.Since HSBCs have good resistance to degradation under UV light exposure,they have good colour stability and can withstand exposure to harsh outdoor environments.HSBCs are suitable for plastics modification for consumer and industrial applications.Not only can they be used in plastics modification,but they are also widely used in adhesives,such as hot melt adhesives(HMAs)and solvent-based adhesives(SBAs).These block copolymers have good physical properties and are compatible with additives such as tackifiers and processing oils.
