Carbon black for plastic color masterbatch

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) PAH (polycyclic aromatic hydrocarbon) content. Carbon black is mainly used as a reinforcing filler in tires and other rubber products. In plastics, paints, and inks carbon black is used as a color pigment.

The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The balance is mainly used as a pigment in inks, coatings and plastics. For example, it is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade.

carbon black should continue to be used in products – including food packaging for consumers. This was because “in most consumer products carbon black is bound in a matrix and unavailable for exposure, for example as a pigment in plastics and rubbers” and “it is proposed that carbon black is not entering the environment in a quantity or concentrations or under conditions that constitute or may constitute a danger to human life or health.”

Zibo Holy Masterbatch Co.,Ltd specilized in producing of black carbon masterbatch for 18 years.  Black color masterbatch can be widely applied to film blowing, blow molding, pipe, injection molding, pressing and other processing. Carbon color master batch is suitable for various polymersincludes polyolefins (HDPE, LDPE, LLDPE, PP, PVC, etc.). It maintaining a good compatibility, dispersion and stability, as well as excellent processability.
