1. Rubber products
Generally most rubber coloring is black, gray or white, these are achromatic colors. In addition, there are many rubber products colored in colors, such as red, blue, yellow, green, brown, pink, etc. The coloring of rubber products can use organic pigments, inorganic pigments and dyes. Today we will mainly discuss organic pigments for rubber coloring. Organic pigments are used for coloring rubber because organic insoluble pigment can create bright and attractive color shades. By choosing the right pigment or mixing pigments, bright colors can be produced. Their advantage is that they produce a more beautiful appearance of the product.

2. The performance of rubber products
①It has good dispersibility in rubber medium, high tinting strength and covering power; excellent dispersibility makes the product have bright shade, high tinting strength, shortens rubber mixing time and reduces energy consumption.
② Excellent heat resistance stability, the colorant should keep the color unchanged during the heating molding process of the rubber product.
③Excellent vulcanization resistance and stability, the colorant does not react with the vulcanizing agent and accelerator. Some inorganic pigments chrome yellow lead or lead-containing pigments react with sulfur to form PBS and turn black, organic pigments should have vulcanization resistance.
④Excellent weather fastness, especially rubber products for building materials used outdoors.
⑤ Good chemical resistance, acid resistance, alkali resistance and water resistance.
⑥ Migration resistance, no color migration or color diffusion (B1eeding) or blooming due to the presence of softening (plasticizer) agents and lubricants during coloring.
⑦Do not affect the anti-aging performance of rubber products, some metal salts such as Cu, and Mn can accelerate the aging of rubber and reduce the mechanical strength.
⑧ Non-toxic, the coloring agent used for children's toys, food containers, medical appliances, and rubber products should not contain toxic substances. The unit cost of making natural paint pigments is much more expensive than inorganic pigments, but to make the color of the rubber color brighter and cleaner, organic pigments are necessary. Organic pigments are difficult to disperse in rubber compounds, and they are dustier in the application. In fact, they are usually used as rubber color master mixes. This pre-dispersed form solves dust problems, greatly improves color uniformity in the final product, and makes colorants easier to weigh and handle.
