Black masterbatch masterbatch, also known as color seed, is an aggregate prepared by uniformly attaching an extraordinary amount of pigment or dye in resin. There are several benefits of using masterbatches:
1. Save time and raw materials;
2. The process is simple and the color change is easy;
3. Make the pigment have better dispersion in plastic;
4. The environment is clean and does not stain utensils;
5. It is conducive to maintaining the chemical stability of pigments and the stability of color.
The masterbatch technology requirements of black masterbatch manufacturers are very strict, and the masterbatch technology generally used is a wet process, and the masterbatch material is made of aqueous grinding, phase transfer, washing, drying and granulation, and only in this way can the product quality be guaranteed. In addition, while grinding pigments, a series of masterbatch technical testing items should also be carried out.
Black masterbatch manufacturers usually add two parts of black masterbatch to the plastic tray during production, adding this masterbatch can enhance the performance of the plastic tray, but also leave some black marks on the surface of the tray. When non-industry personnel find these black marks, they usually only wonder whether the manufacturer has added recycled materials to the pallets, whether these pallets are defective products that cut corners, and so on.
In fact, the black masterbatch is not a recycled material, it is a formula that can be used with anti-aging additives, according to the length of time the tray is used outdoors, determines the amount of black masterbatch, and the carbon black in the black masterbatch forms a continuous phase in the product, forming a layer of film to protect the plastic and block the exposure of ultraviolet rays. Therefore, the plastic pallet produced with it has the characteristics of anti-aging, which greatly improves the service life of the plastic pallet.
