Fine-Blend SBG-001 Impact Modifier

SBG-001 is a unique core-shell impact modifier with high compatibility to polycarbonate. This product is manufactured by Fine-Blend and exclusively distributed in North America by SACO AEI Polymers Distribution.

PC/ABS provides a synergic balance of processability and toughness, with the high heat distortion temperature of the polycarbonates 

• ABS rubber content > impact properties increase
• PC/ABS ratio > thermal properties increase

The goal is to add more rubber content into the dominate PC phase. 

Core-Shell Structure:

• Butadiene rubber core (Tg= -80 degrees Celsius) for impact performance 
• SAN-GMA copolymer shell for compatibility with PC

Styrene-AcryoNitrile-Glycidyl MethAcrylate shell: the GMA (epoxy) groups can react with the polycarbonate end-groups, resulting in an effective dispersion of the rubber into the PC phase, thus optimal impact performance. 

Impact Strength in 70/30 PC/ABS:

Fine-Blend SBG-001 can gently stabilize the morphology of the polymer blend, thus resulting in: 

•     Toughening efficiency (better than conventional MBS impact modifiers)
•     Improve heat stability and hydrolytic resistance
•     Less surface defects

A 3% of SBG-001 is also effective in upgrading the impact properties of recycled PC/ABS
