General Description:

Oil-extended SBS is a triblock copolymer composed of styrene hard segments and butadiene soft segments, extended with high-quality naphthenic or paraffinic oil during the polymerization process. Synthesized from styrene and butadiene monomers via anionic polymerization, this material combines the structural strength of plastic with the dynamic elasticity of rubber. The precise oil extension improves flow properties and reduces melt viscosity, making it easier to process without sacrificing essential mechanical integrity.

Key Features & Benefits:

Superior Processability: Excellent flow characteristics optimize cycle times in injection molding and extrusion.

High Elasticity & Flexibility: Maintains rubber-like properties and flexibility even at low temperatures.

Cost-Effective Formulation: High oil content allows for increased filler loading, significantly reducing overall compound costs.

Strong Adhesion: Exceptional bonding capabilities make it ideal for multi-material applications.

Reliable Supply Chain: Backed by Fujian Hongkong Petrochemical Limited, we ensure consistent quality and availability.

Applications:

Footwear: The primary choice for shoe soles (TPR) requiring high grip, abrasion resistance, and comfort.

Consumer Goods: Perfect for soft-touch grips on tools, toys, and automotive interior parts.

Plastic Compounding: Ideal for modifying thermoplastics to improve impact resistance, flexibility, and melt flow.
