For the carbon black masterbatch carrier, a linear polyethylene LLDPE with a wide applicability is generally used. LLDPE resin as a carrier is conducive to the dispersion and processing of carbon black. It is also more suitable for extrusion blown film. After grafting, it is also used for HIPS ABS PP LDPE HDPE. The carbon black masterbatch is generally chosen to be a resin with a melt index similar to that of a plastic matrix resin, and it is best to choose the same resin as the carrier.
When you want to get a black glossy plastic product, choose a low-structure carbon black with a small particle size. This is because when carbon black is colored, the blackness is mainly based on the absorption of light. Therefore, at a certain concentration of carbon black, the smaller the particle size, the higher the degree of light absorption, the weaker the light reflection, and the higher the blackness, in order to obtain satisfaction.
