          Requirements of Masterbatch Colors for Pornography


          (1) Colors can not react with resins and various additives. They have strong solvent resistance, small migration and good heat resistance. In other words, color masterbatches can not participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastics, so carbon black can not be added to polyester.

          PLASBLAK? PE6021 contains high concentration carbon black, which not only provides excellent dyeing strength and covering ability, but also maintains the mechanical properties of basic plastics. With the different quality of the reconstituted resin, the amount of the masterbatch can be reduced by 10-15% compared with the current product, and the same colouring effect can be achieved. In order to maintain the mechanical properties of basic plastics, such as tension strength and high processing temperature of plastic products, the color material should not decompose and discolor at heating temperature. Generally, inorganic pigments have good heat resistance, while organic pigments and dyes have poor heat resistance, which should be paid enough attention to when choosing color varieties.

          (2) The dispersibility and dyeing power of the pigments should be good. When the color is not uniformly dispersed, it will affect the appearance of the product; when the dyeing power is poor, it will increase the amount of color and material cost. The dispersibility and dyeing power of the same colour in different resins are different, so we should pay attention to this when choosing the colour.

          The particle size of pigments is also related to dispersion. The smaller the particle size of pigments, the better the dispersion and the stronger the dyeing power.

          (3) We should know the other properties of pigments, such as non-toxic pigments for plastic products used in food and children's toys, good electrical insulation pigments for plastic products used in electrical appliances, and good weather aging resistance pigments for outdoor plastic products.
