What are the raw materials and uses of color masterbatches? Currently, many consumers have such questions. We all know that color masterbatches are plastic colorants made from a high proportion of pigments or additives and thermoplastic resins, which are well dispersed. The resins selected have good wetting and dispersing effects on the colorants, and have good compatibility with the colored materials. So what are the raw materials and uses of color masterbatches?
First, what is the raw material of the color master batch?
Generally speaking, color masterbatches are colored plastic particles that are granulated after mixing resin raw materials and pigment additives in factories. Their main function is to color. Because they have been mixed evenly with the matrix resin, users can directly blend with the matrix resin and other additives to obtain colored plastic products. Namely, color masterbatch is the raw material of plastic colorants.
What are the uses of color masterbatches?
Color masterbatches can be used for color matching of PVC, polyethylene, polypropylene, polystyrene, and ABS plastics. Its main components include pigments, resins, dispersants, bulk pigments, fluorescent brighteners, antioxidants, anti ultraviolet agents, antistatic agents, toughening agents, brighteners, etc. Titanium dioxide is used as a white pigment, with the advantages of non-toxic, stable chemical properties, high hiding power, and good dispersibility.
Color masterbatches can replace previous plastic colorants, with many advantages as follows:
Firstly, it makes pigments have better dispersibility in products.
During the production process of color masterbatch, it is necessary to refine the pigment to improve its dispersibility and coloring power. The carrier of the special color masterbatch is the same as the plastic variety of the product, with good compatibility. After heating and melting, the pigment particles can be well dispersed in the plastic of the product.
2. Helps to maintain the chemical stability of pigments.
When using pigments directly, due to their direct contact with air during storage and use, the pigments can absorb water and oxidize. After becoming a color master, the resin carrier can isolate the pigments from air and moisture, allowing the quality of the pigments to remain unchanged for a long time.
3. Ensure the stability of product color
Color masterbatch particles are similar to resin particles, making them more convenient and accurate in measurement. When mixed, they will not adhere to the container, and the mixture with the resin is relatively uniform. Therefore, it can ensure the stability of the addition amount, thereby ensuring the stability of the product color
