Main performance requirements for pigments used in plastic masterbatches

TIme:2023-06--28
1. Coloring power The coloring power of a pigment refers to the amount of pigment required for a certain color product, expressed as a percentage of the coloring power of a standard sample. The coloring power of a pigment is not only related to its properties, but also to its degree of dispersion. The degree of dispersion mainly refers to the degree of refinement of the pigment. The greater the degree of dispersion, the stronger its coloring power, but it has a saturation value. 2. Heat resistance Heat resistance refers to the degree of change in the color or performance of pigments under processing and usage temperatures. When considering the heat resistance of pigments, it is also important to consider their heating time. Due to the different processing methods and heating times of plastics when processed into products, and the different uses and heating times during use, the higher the temperature used, the shorter the heat resistance time. 3. Migration resistance The migration resistance of pigments refers to that the colored plastics may have physical and chemical reactions with the above substances when they are in long-term contact with other solid, liquid, gas and other substances or when they work in a specific environment, which is manifested by the migration of pigments from the inside of plastics to the Free surface of products, or to the adjacent plastics or solvents. 4. Light resistance and weather resistance Plastic products require good light and weather resistance due to long-term outdoor use. Some pigments undergo varying degrees of color changes under light exposure. Weathering resistance refers to the color stability of pigments under natural conditions. Due to its extensive outdoor use, the black mother pays special attention to migration resistance and weather resistance.

What is color masterbatch? Why use color masterbatch?

TIme:2023-06--28
Color mother, also known as color species, It is an aggregate made by uniformly attaching super constant pigments or dyes to branches, Several benefits of using color masterbatch: Helps to maintain the chemical stability of pigments; Better dispersion of pigments in plastic; Protect the health of operators; The process is simple, the color change is easy, the environment is clean, and the utensils are not contaminated; Save time and raw materials. Due to the direct contact between pigments and air during storage and use, As a result, phenomena such as moisture absorption, oxidation, and agglomeration will occur, Direct use will cause color spots on the surface of plastic products, resulting in a darker hue and easy color fading, And it causes dust to fly during mixing, affecting the health of operators, And the color masterbatch undergoes mechanical processing during the production process, The pigment has been refined and thoroughly mixed with branch carriers and dispersants, Isolates pigments from air and moisture, thereby enhancing their weather resistance Improved the dispersibility and coloring power of pigments, resulting in a bright hue. Due to the similarity in shape between the color masterbatch and the branch particles, So it is more convenient and accurate in measurement, and it will not adhere to the container during mixing, Therefore, it saves cleaning time and raw materials used for cleaning the machine.
