At present, many consumers have such doubts. 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 used have good wetting and dispersing effects on the colorants, and have good compatibility with the colored materials. So what are the raw materials and the uses of color masterbatches? Today, i will explain to you:
Firstly, what are the raw materials for color masterbatches?
Generally speaking, color masterbatch is a colored plastic particle made by mixing resin raw materials and pigment additives in factories. Its main function is to color. As it has been evenly mixed 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 for plastic colorants.
Secondly, what are the uses of color masterbatches?
Color masterbatch can be used for color matching of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and ABS plastics. Its main components include pigments, resins, dispersants, bulk pigments, fluorescent whitening agents, antioxidants, anti ultraviolet agents, antistatic agent, toughening agents, brighteners, etc. titanium dioxide is used as a white pigment, which has the advantages of non-toxic, stable chemical properties, high hiding power, good dispersion, etc.
Color masterbatch can replace previous plastic colorants, and there are many advantages as follows:
Firstly, it enhances the dispersibility of pigments in products.
1. During the production process of color masterbatch, it is necessary to refine the pigments to improve their dispersibility and coloring power. The carrier of the specialized color masterbatch is the same as the plastic variety of the product, and has good compatibility. After heating and melting, the pigment particles can be well dispersed in the plastic of the product.
2. It is conducive to maintaining the chemical stability of pigments.
If pigments are directly used, due to direct contact with air during storage and use, the pigments will experience water absorption, oxidation, and other phenomena. After being made into color masterbatch, the resin carrier separates the pigments from air and water, which can maintain the quality of the pigments 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 do not adhere to the container, and the mixing with the resin is also more uniform. Therefore, the stability of the addition amount can be ensured, thereby ensuring the stability of the product color
