Stereon™

Styrene Butadiene Modifier for Plastics

Stereon™ 721AC is a low styrene block copolymer with a low solution viscosity. Providing excellent performance for impact enhancement of styrene based polymers. The low viscosity allows:

• Higher loading of rubber than standard Diene™ polymers
• Smaller particle size potential
• Maintenance of impact resistance
