Experiments of the preparation of black masterbatch carbon black content is 35%, the variety and dosage of dispersants decide by experiment, carrier resin is low density polyethylene.
The characteristics of black masterbatch are:high concentration, easy to spread, and add quantity is little, and after adding them,chemical purity and pressure resistance, anti aging, mixing ingredients hermal ,performance indicators, conform to and meet the requirements of water supply with polyethylene pipe mixed special material. According to the formula, with the same material as the carrier, to join the high pigment carbon black, antioxidant, carbon black, dispersant, processing AIDS, etc through twin-screw mixing and fully. Widely used in PE, PP, PS, ABS, PA, PBT, PET, PC, POM, EVA and PPO, blow molding, extrusion, injection, etc. Features: good dispersibility, high blackness, good dyeing force, prevent ultraviolet, prevent aging.
