General Purpose GPPS Color Masterbatch
Standard GPPS masterbatch for injection molding and extrusion with bright color development.
Our GPPS color masterbatch delivers bright, consistent colors for general-purpose polystyrene applications. The carrier system is designed for easy dispersion in GPPS resin, providing uniform color with low addition rates.
Product Features
- Good color development at low addition rates (2%)
- Low haze for translucent applications
- Compatible with standard GPPS grades
- Fast color change capability
- Food-contact grades available (FDA)
