What is Plastic Masterbatch?
Plastic masterbatch is a concentrated mixture of pigments/additives uniformly dispersed in a carrier resin, used to color or enhance polymer properties. Our masterbatches deliver:
- Vibrant, consistent colors (ΔE<1.5 batch-to-batch)
- Superior processability (No filter clogging, MFI 5-30 g/10min)
- Regulatory compliance (FDA, REACH, RoHS, UL)
50% Faster Dispersion – Patented extrusion technology
Global Stock – 3,000+ pre-mixed colors, 72hr sample service
Tech Support – Free formulation consulting
