Glass Fiber Reinforced PBT Color Masterbatch
GF-PBT masterbatch for connectors, sensor housings, and structural electronic components.
Our GF-PBT color masterbatch is optimized for glass-fiber reinforced PBT composites. It provides good pigment dispersion in the GF matrix while maintaining mechanical properties for connectors and structural electronic components.
Product Features
- Good dispersion in GF matrix (up to 30% GF)
- Maintains mechanical properties
- Excellent electrical insulation
- Good dimensional stability
- Warpage control formulation
