SBS YH-791E, YH-792E and YH-796E are all linear styrene-butadiene-styrene block copolymers. They are widely used in adhesives, polymer modification and bitumen applications. The main difference between these three grades is their styrene content, which leads to different balances of hardness, flexib
1. How to Select SEBS for Heat-Resistant TPE1.1 Molecular ArchitectureWhen heat resistance is required, the molecular architecture of SEBS is an important factor. However, it should not be oversimplified as “star-shaped SEBS is always better.” In SEBS-based TPEs, the styrene domains mainly act as ph
In the production of asphalt waterproofing membranes, SBS (Styrene-Butadiene-Styrene) has long dominated the mainstream market due to its cost-effectiveness. However, despite the higher price tag of SIS (Styrene-Isoprene-Styrene), many projects still prioritize it over SBS.Why? Because SIS precisely
