Three Core Applications

1. Plastic Modification

SBS 3566 serves as a key impact modifier for PP, PE, PS and other commodity plastics. It significantly improves impact resistance and low-temperature toughness while maintaining basic mechanical properties. Ideal for modified plastics requiring high impact strength and cold temperature performance.

2. Asphalt Modification

Widely used in asphalt modification applications, SBS 3566 enhances the elasticity, elongation, and high/low-temperature performance of asphalt. It is extensively used in road asphalt modification and waterproofing membrane production. The superior low-temperature properties maintain flexibility and crack resistance even in extreme cold conditions.

3. Adhesives

With low viscosity and good solubility, SBS 3566 is an ideal base polymer for hot melt adhesives, pressure-sensitive adhesives, and contact adhesives. It provides excellent initial tack, holding power, and cohesive strength, suitable for footwear, packaging, hygiene, and other industries.
