Optical Grade GPPS Color Masterbatch
Ultra-low haze formulation for optical lenses, lighting diffusers, and high-end displays.
Our optical-grade GPPS masterbatch uses ultra-low haze pigments specifically selected for applications requiring pristine optical clarity. It minimizes impact on light transmission while providing consistent, vibrant color.
Product Features
- Ultra-low haze (< 3%)
- Minimal effect on light transmission
- High-end display applications
- Consistent color at low addition
- Suitable for injection and extrusion
