How to Prepare SBS for Production of Adhesives?

How to Prepare SBS for Production of Adhesives?

Styrene-butadiene-styrene triblock copolymer (SBS) possesses features of both thermoplastics and vulcanized rubber owing to the solubility and thermoplasticity of polystyrene (PS) and the toughness and resilience of  polybutadiene (PB). The features result from the incompatibility of thermodynamics between the end of PS molecular chain and the middle of PB molecular chain. The end of PS molecular…

Technology and Applications of SBS-based Adhesives

Technology and Applications of SBS-based Adhesives

SBS refers to styrene-butadiene-styrene triblock copolymer. It is a type of thermoplastic elastomer, generally called “thermoplastic styrene-butadiene rubber” and well-known as “the third generation of synthetic rubber”. SBS has both plastic and rubbery properties, showing plasticity at high temperature and elasticity at room temperature. It exhibits properties of thermoplastics without…

SBS Modification by PE / PP / PS

SBS Modification by PE / PP / PS

Why SBS needs to be modified by adding plastic products? This mainly results from its poor processing performance and product properties that can’t meet the practical application requirements. In general, SBS is rarely used in the finished products independently. To satisfy the special requirements of applications and reduce costs, SBS must be modified by adding additives, resins and others. With…

Requirements for Ingredients in Production of SBS Granules for Shoe Soles

Requirements for Ingredients in Production of SBS Granules for Shoe Soles

SBS, the major raw material for SBS-based TPR footwear, provides strength, elasticity and other performance for footwear. SBS grade YH-815,   SBS T171 are frequently used for production of SBS-based TPR footwear. However, the specific grades should be selected based on manufacturers’ requirements for footwear, including costs, performance, sole type, etc. Softening Oil Softening oil is mainly…
