PBT masterbatch is a highly concentrated blend of pigments or additives encapsulated in a PBT-compatible carrier resin. It is designed to provide uniform coloring and functional modification during the processing of PBT materials through injection molding, extrusion, or compounding.
Rongfeng PBT masterbatches are engineered to withstand the relatively high processing temperatures required for PBT polymers, ensuring stable color performance and preventing pigment degradation during production.
Our product range includes:
- PBT Color Masterbatch
- PBT Black Masterbatch
- PBT White Masterbatch
- PBT Functional Masterbatch (UV resistant, flame retardant compatible, anti-static, etc.)
- Custom Color Matching Masterbatch
Key Features
- Excellent Heat Resistance – Suitable for high-temperature PBT processing environments.
- Superior Pigment Dispersion – Ensures uniform color distribution without streaks or spots.
