Masterbatch coloring dye coloring ratio has many advantages, and with the development of plastics processing industry, in particular the establishment of a number of joint ventures and export products increased requirements for coloring, colored masterbatch increasingly dominant, it masterbatch applicability classification, it can be divided into general and special masterbatch masterbatch.

Special masterbatch
When manufacturing masterbatch, selection and want colored resin the same resin as the carrier, added to the high concentration of pigment (dye), under the effect of additives, by heating, plasticizing, kneading, extrusion granulation, made specially suited for this type of resin dye, called special masterbatch. Special masterbatch concentration can be high or low, add the amount generally between 1% to 4%.

Universal masterbatch
The main difference between universal masterbatch (also known as "universal masterbatch") and special masterbatch is: universal masterbatch although in some resin as a carrier, but it can be applied to coloring in addition to its carrier resin other resins , so called universal masterbatch.

The so-called universal masterbatch, in general, the following measures (some manufacturing plants simply do not have as a carrier resin, and all for a carrier with a high melting point wax propylene): First selection of low melting point, high melt index of the resin as a universal masterbatch Second, the pigment powder masterbatch ratio as high as possible, and therefore must be the universal masterbatch high concentration masterbatch, the amount used in the injection molded article is generally 1%; carriers, such as PE or EVA. Due to the different media masterbatch carrier is very small (less additive factors, usually around 20%), then the content when it is diluted in the ratio of 1% For colored resins, plastics contained within the different resins : 0.2kg / 100 = 2g / kg. In order to make universal masterbatch can be combined with other types of pigmented resin good (good compatibility), we also used the universal masterbatch other measures, such as adding special effects and more coupling agents, prolonged mixing time, etc. these are conducive to improving the broad applicability of universal masterbatch.
