styrene-butadiene-styrene triblock copolymer
polymerStyrene-butadiene-styrene (SBS) is a thermoplastic elastomer consisting of hard polystyrene end blocks connected to a soft polybutadiene middle block, combining rubber-like elasticity with plastic processability. It is widely used in adhesives, footwear soles, roofing membranes, and impact-modified plastics where a balance of flexibility, resilience, and processability is required. Engineers select SBS over conventional rubbers when ease of processing and recycling are priorities, and over rigid plastics when impact resistance and damping are needed.

Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
