Although SBR (Styrene-Butadiene Rubber) and SBS (Styrene-Butadiene-Styrene) are both synthesized from styrene and butadiene, their molecular structures result in fundamentally different material properties and processing behaviors.Molecular StructureSBR is a random copolymer, with styrene and butadi
As India accelerates its national infrastructure development, demand for high-performance road materials continues to rise—particularly Polymer Modified Bitumen (PMB), which has driven a significant increase in SBS (Styrene-Butadiene-Styrene) consumption. Today, India stands as one of the fastest-gr
HUNAN TOLL CHEMICAL CO., LTD is delighted to share the successful outcome of our participation in BITUROAD 2025, held in Vietnam. As one of the key events in the global asphalt and road materials industry, the conference brought together leading experts, suppliers, and partners from around the world
Styrene-Butadiene-Styrene (SBS) is a thermoplastic elastomer which is widely used in the production of polymer modified bitumen (PMB). Its unique molecular structure — consisting of hard polystyrene end blocks and soft polybutadiene mid blocks — It let bitumen/asphalt has both elasticity and flexibi
