Stereon™ 721AC
- Chemical Family
- ButadienesStyrenic Block Copolymers
Stereon™721AC is a solution polymerized styrene-butadiene block copolymer that has been designed as an impact modifier for thermoplastic ABS resin. The low solution viscosity of this product makes it particularly attractive for high rubber loading systems. Stereon™721AC also contains a non-volatile antioxidant stabilizer system and has a very low gel content.
