What is the raw material of color masterbatch and what are the uses of color masterbatch? At present, many consumers have such a question, we all know that the masterbatch is made of a high proportion of pigments or additives and thermoplastic resins, through a good dispersion of plastic colorants, the selected resin has a good wetting and dispersing effect on the coloring agent, and has good compatibility with the coloring material. So in the end, what is the raw material of color masterbatch and what are the uses of color masterbatch?
First, what kind of raw material is masterbatch?
Generally speaking, masterbatch is a plastic particle with color which is mixed with resin raw material and pigment additives and then granulated, and its main role is coloring, because it has been mixed evenly with the base resin, and thus the user can directly mix with the base resin and other additives to get the plastic products with color. That is: masterbatch is the raw material of plastic colorant.
Second, what are the uses of masterbatches?
Color masterbatch can be used to match the color of PVC, polyethylene, polypropylene, polystyrene and ABS plastics. Its main ingredients are pigment, resin, dispersant, volumetric pigment, fluorescent whitening agent, antioxidant, anti-ultraviolet agent, antistatic agent, toughening agent, brightening agent, etc. Titanium dioxide is used as a white pigment in it, which has the advantages of non-toxicity, stable chemical properties, high covering power, good dispersion and so on.
Color masterbatch can replace the previous plastic coloring agent, there are many advantages as follows:
First of all, it makes the pigment have better dispersion in the products.
The pigment must be refined during the production process of color masterbatch to improve the dispersibility and coloring power of the pigment. The carrier of special color masterbatch is the same as the plastic species of the products, which has good matching, and the pigment particles can be well dispersed in the plastic of the products after heating and melting.
2. It is good for keeping the chemical stability of pigment.
If the pigment is used directly, it will absorb water and oxidize due to direct contact with air in the process of storage and use, but after it is made into masterbatch, it can keep the quality of pigment unchanged for a long time due to the isolation of pigment from air and water by resin carrier.
3. Ensure the stability of product color
The masterbatch particles are similar to the resin particles, so it is more convenient and accurate in measuring, it will not stick to the container when mixing, and the mixing with the resin is more uniform, so it can guarantee the stability of the added quantity, thus guaranteeing the stability of the color of the products.
