Black masterbatch is made of imported high-pigmented carbon black, brand-new polyethylene resin and imported pigments additives by high-speed mixing, extrusion and water-cooled drawing strip granulation, with a carbon black content of 45%.

The color masterbatch is a plastic colouring agent which is well dispersed by high proportion of pigments or additives and thermoplastic resins. The resin selected by the masterbatch has good wetting and dispersing effect on the colouring agent and good compatibility with the coloured material. That is: pigments + carriers + additives = color masterbatch.
