I. What is a universal color masterbatch
Color masterbatch is an aggregate made by evenly loading a high proportion of pigments onto resin. It can be divided into general-purpose color masterbatch and special-purpose color masterbatch. The so-called general-purpose color masterbatch is a color masterbatch with a certain resin as the carrier, which can be applied to the coloring of other resins except its carrier resin.
Although the general-purpose masterbatch is called "general-purpose", in reality, its scope of application is relatively narrow, and its technical indicators and economic benefits are also poor. Specifically, it is manifested in the poor predictability of the coloring effect and the impact on other properties of plastic products. Therefore, many masterbatch companies generally do not produce general-purpose masterbatches.
Ii. What is used as the carrier for universal color masterbatches
The carrier of a color masterbatch refers to the matrix of the color masterbatch. Special color masterbatches usually choose the same resin as the product resin as the carrier, and the compatibility between the two is the best. General-purpose color masterbatches are relatively simple and convenient. So, what kind of resin is generally used as the carrier for general-purpose color masterbatches?
Generally speaking, the carriers of general-purpose color masterbatches can be applied to the coloring of various resins. The carriers can be low-melting-point PE, low-molecular-weight polyethylene wax, EVA, K resin, metal soaps, or a combination of two or three of the above carriers.
Iii. What are the carrier requirements for general-purpose color masterbatches
General-purpose masterbatches usually use resin materials as carriers. Regardless of the type of resin, the basic requirements are as follows:
It can effectively disperse colorants and granulate them.
2. It has good compatibility with the plastics that need to be colored.
3. Good liquidity.
4. When color masterbatches are used for plastic coloring, improper use of carriers should not have a negative impact on the physical and mechanical properties and other characteristics of plastic products.
