Other additives include coupling agents, antioxidants, light stabilizers, antistatic agents, fillers, etc., depending on the requirements and variety, called multi-functional masterbatch, and if added brightener, it is beneficial to molded products. Demolding and improving the brightness of the surface of the product.
The performance indicators of the masterbatch in plastic color matching are color difference, whiteness, yellowness, yellowing degree, thermal stability, oxygen index, melt flow rate, etc. Of course, the fineness, migration, chemical resistance and toxicity of the pigment are also It is related to the properties of masterbatch, and some indicators are very important in special applications, such as the filter density (DF value) fineness of fiber grade masterbatch.
In general, due to the development requirements of environmental protection and quality, the current plastic color matching manufacturers have chosen more and more masterbatch color matching methods, which will bring more market space for masterbatch color matching companies.
