SEBS (Styrene-Ethylene/Butylene-Styrene)
Product Overview
SEBS (Styrene-Ethylene/Butylene-Styrene block copolymer) is a thermoplastic elastomer that combines the processing characteristics of thermoplastics with the functional performance of vulcanized rubber. SEBS offers excellent weather and heat resistance, high mechanical strength, and good compatibility with plastics. It is a linear and clear block copolymer that provides superior performance in various applications including plastic modification, compounding, asphalt modification, and adhesives.
