Pigments are insoluble organic or inorganic particles added to the polymer base to give a specific color to the plastic. Pigments that are organic in nature are hard to disperse and tend to form agglomerates (clumps of pigment particles). These agglomerates can cause spots and specks in the final product. On the other hand, inorganic pigments like: Metal oxides and sulphides, carbon black, etc. get more easily dispersed in the resin. Amongst the inorganic pigments titanium dioxide is the most widely used pigment in the plastics industry.
Sudarshan Company is one of the largest producers of pigments, which, due to the variety of production, is known as one of the best in the field of producing organic pigments without heavy metals and traditional inorganic. Sudarshan's range of high-performance pigments and solvent dyes complements the material's superior performance with high thermal stability and excellent light stability, while increasing processing stability.
One of the best pigments is DCai products. In addition to having a very good performance for all paint, printing, and ink industries, it also has excellent performance for masterbatch and compounds. The products of this company are organic and inorganic. The methods of measuring the relative data of pigments (pigments), micro shapes, appearance and crystal line, appearance properties of pigments, easy dispersion are among the most common methods in this company.
