CAS 9003-55-8

Butadiene-styrene copolymer

Description:

Butadiene-styrene copolymer (CAS 9003-55-8), commonly known as SBS (styrene-butadiene-styrene), is a thermoplastic elastomer that combines the properties of rubber and plastic. It is synthesized through the copolymerization of styrene and butadiene, resulting in a material that exhibits excellent elasticity, resilience, and flexibility. SBS is characterized by its high tensile strength and good abrasion resistance, making it suitable for various applications, including adhesives, sealants, and coatings. The copolymer's structure consists of hard polystyrene domains that provide strength and soft polybutadiene segments that impart elasticity. SBS is also known for its compatibility with other polymers and additives, enhancing its versatility in formulations. Additionally, it has good thermal stability and can be processed using standard thermoplastic techniques, such as extrusion and injection molding. However, it is sensitive to UV light and can degrade over time when exposed to harsh environmental conditions, necessitating the use of stabilizers or protective coatings in certain applications.
