PBT Black Masterbatch / PP (Polypropylene) Black Masterbatch (Spinning Grade)
PBT black masterbatch consists of high-concentration carbon black, PBT carrier resin, and advanced dispersants. Produced via twin-screw extrusion, it ensures uniform pigment dispersion, providing high color depth, heat resistance , and mechanical stability. Ideal for PBT engineering plastics in electronics (connectors, switches), automotive components, and industrial parts, meeting requirements for UV resistance and flame retardancy. Eco-friendly options comply with RoHS.
PP black masterbatch (fiber grade) combines highly dispersible carbon black, high-flow PP homopolymer carrier, and specialized dispersants. Optimized for polypropylene fiber spinning, it undergoes high-shear processing to eliminate gel particles and ensure low VOC emissions, compatible with high-speed spinning. Provides uniform coloration, high tensile strength, and light resistance. Used in apparel, non-woven fabrics, and industrial fibers.
