Cobalt green pigment usually does not change color at high temperatures, thanks to its excellent heat resistance. Cobalt green pigment is an important high-performance and environmentally friendly inorganic pigment, and is the highest performing pigment among all green pigments. Its notable features are outstanding heat resistance, light resistance, weather resistance, and chemical resistance. These characteristics enable cobalt green pigments to maintain stable color performance in various high-temperature environments.

Engineering plastic coloring: Cobalt blue pigment can be used for coloring engineering plastics, such as polyamide (nylon PA), polycarbonate (PC), polyphenylene ether (PPE or PPO), polyester (PET, PBT), polyoxymethylene (POM), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyarylester (PAT or PAR), etc; Provide bright and durable blue color for plastic products, while meeting the high requirements of engineering plastics for pigment performance.

What are the differences in color and performance between phthalocyanine blue and ultramarine blue, both of which are blue coloring pigments? The difference between the two mainly depends on the following aspects. From the perspective of color, phthalocyanine blue is dark blue, while turquoise blue is light blue. There are three colors of phthalocyanine blue: red, purple, and green. Generally speaking, there is only one color of turquoise blue - red. The difference in hue has a significant impact on the actual performance of these two types of blue color powders when used.

Why does ultramarine pigment have an odor? Turquoise blue pigment is an ancient and vibrant blue pigment, as well as a common mineral pigment. Early turquoise came from ground lapis lazuli, which is a sodium aluminum sulfide silicate. In the West, its color symbolizes the Virgin Mary and has important religious significance. Due to the rarity of lapis lazuli, the price of ultramarine remained high until the 19th century when people innovatively invented artificially synthesized ultramarine.

The application of ultramarine pigment and hydrophilic ultramarine pigment inorganic blue pigment. The paint industry is used to manufacture colored paints, making the whiteness more vivid. The rubber industry is used for coloring, whitening, or blending with yellow pigment to create a grass green color for rubber products such as shoe soles and rubber sheets. The paper industry uses it in pulp to produce bright white or blue pulp. The printing and dyeing textile industry uses white cotton and knitted fabrics to increase fiber whiteness and print trademarks on knitted fabrics.

The performance of materials is closely related to injection molding conditions and product quality. Most injection molding materials are in granular form. When these solid materials are loaded into the hopper, they are generally preheated to remove moisture, and then compressed and plasticized by the screw. They need to go through a long thermal process in the barrel before being pushed into the mold cavity by the screw, and then cooled and shaped after the pressure holding stage. The main factors affecting this process are materials, temperature, barrel temperature, filling pressure, and speed.
