Thermoplastic Elastomers (TPEs)
Product Overview
SEBS (Styrene–Ethylene–Butylene–Styrene) based oil-extended Thermoplastic Elastomers are high-performance materials that provide excellent elasticity, soft touch, and outstanding weather resistance.
This product series is formulated with high-purity white oil / paraffinic oil, combining rubber-like flexibility with the processing advantages of thermoplastics.
It is an environmentally friendly elastomer designed to replace conventional vulcanized rubber and is suitable for injection molding, extrusion, and calendaring processes.
