The masterbatch carrier, usually polymers, the role of the carrier is the "bearer" colorant and various auxiliary components, coloring agent components and to obtain good dispersion of the components in the carrier adhesion granulation , to prevent dust, easy to use purpose.
Masterbatch carrier, generally used the same polymer and plastics coloring needs, the basic requirements of the masterbatch carrier listed below.
(1) can be finely dispersed colorant and make it into tablets;
Having good compatibility between (2) and the required colored plastic;
(3) better mobility;
As the need to use the same plastic colored polymer as the carrier, the molecular weight should be below the new colored plastic (melt flow rate greater than the required vector colored plastics melt flow rate); When the carrier and the desired colored plastic When different polymer, the melting point of the carrier is lower than the melting point of the colored plastic, and at the same temperature, the melt flowability of the carrier, is higher than the required colored plastic melt fluidity; prepared in After the masterbatch, masterbatch melt flow rate, generally should be 2-5 times the desired colored plastic melt flow rate;
(4) When the masterbatch for coloring plastics, the carrier shall not be due to improper use, resulting in a negative impact on the physical and mechanical properties of plastics and other characteristics.
