Pigment is the main component of masterbatch, there are mainly two categories: inorganic pigments and organic pigments(Pigment Carbon Black). Inorganic pigments for metal oxide and sulfide or metal salt, commonly has better light fastness and weather resistance, this for poor light resistance of polypropylene resin is of great significance. The downside is particle size; Organic pigments have strong tinting strength, good dispersibility, colour and lustre bright-coloured, but its light tends to cause desaturation, easy create shading products fade, suggest to choose suitable inorganic pigment particle size.
Paint the heat resistance of mean temperature in the production or use the color of the paint or performance change of temperature, its heat resistance at 250 ℃, the non-ferrous products color small; At the same time, the selected pigment resistance transference to > 5, light fastness level 6 ~ 8, has good compatibility with polypropylene resin, good synergistic effect with other additives, firmly in the process of spinning processing staining.(Speciality Carbon Black) For medical and penetration, cannot contain in pigment with a health hazard of heavy metal elements, such as cadmium, lead, mercury, etc. Pigment particle size directly influence on the performance of the pigment dispersion degree and finished product, if the pigment particle size is too small, specific surface area, surface free energy is bigger, is easy to gather together and cause its poor dispersion in polypropylene resin; If the pigment particle size is big, will be in production blocking filter plate and the nozzle, makes the fiber increase, the broken ends when stretched wool yarn and make even resin or additives due to stay a long time and cause thermal decomposition, affect the physical and mechanical properties of the fiber. Pigment particles generally control the average particle size of 0.1 m - 0.5/1.
