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
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
Product OverviewSINOPEC SBS 1801E is a linear styrene-butadiene-styrene (SBS) block copolymer specifically engineered for asphalt modification and waterproofing applications. With its stable structure, high elasticity, and outstanding compatibility with various grades of bitumen, 1801E has become on
