White masterbatch: The "Color Magician" of plastic products!
In the colorful world of plastic products, White masterbatch is like a magical "color magician", though unknown, it plays a crucial role.
White masterbatch is essentially a colorant for plastic products. Its main components include white pigments, carrier resins and various additives. Among white pigments, titanium dioxide has become the main force due to its excellent covering power and gloss, endowing plastic products with a pure and bright white appearance. Zinc oxide, with its excellent whiteness and luster, adds a touch of refinement to the product. The carrier resin acts as an adhesive, evenly dispersing the pigment in it to ensure uniform color of plastic products. Dispersants, lubricants and other additives make pigments easier to disperse during the production process, improving product quality and production efficiency.
The performance of white masterbatch is extremely outstanding. The whiteness is simply unparalleled. Whether it is the food packaging as white as snow or the pure and elegant shell of household appliances, it can precisely present the required white and is not prone to yellowing. It has excellent dispersibility. During the processing of plastic products, it can be evenly integrated into the plastic substrate, avoiding defects such as color spots and stripes, and making the product surface smooth and flat. It has good heat resistance and can withstand the high temperatures during the processing of common plastic products. In an environment of 200-300 ℃, it remains stable, does not decompose or discolor, ensuring smooth production. The migration resistance is no less than grade 4, and the sun resistance reaches grades 4 to 8. This means that when used for outdoor plastic products, they can resist light and temperature differences for a long time, maintain consistent color, and extend the service life of the products.
Its application is extremely extensive. In the packaging field, for milk films and beverage bottle packaging, white masterbatch gives the packaging a pure white appearance, attracting consumers' attention and also protecting the contents from the influence of light. In the injection molding industry, from everyday plastic tableware to complex electrical appliance casings, white masterbatch ensures that the products have pure colors and excellent textures. In pipe production, enhancing the weather resistance of pipes ensures that water supply and drainage pipes maintain a good appearance and performance in outdoor environments.
When using White masterbatch, it is only necessary to mix it evenly with the raw resin in a certain proportion (usually 1:10-50, depending on the product requirements), and dry it if necessary. Then it can be put into production. The operation is simple and convenient. It can not only ensure the dispersion of pigments and the stability of product color, but also maintain the chemical stability of pigments and additives, reduce labor intensity, and facilitate the realization of automated production.
With the concept of environmental protection deeply rooted in people's hearts, white masterbatch is also constantly innovating. Nowadays, many enterprises are developing more environmentally friendly production processes, adopting degradable carrier resins to reduce their impact on the environment and meet the market's demand for green products. In the future, white masterbatch will continue to forge ahead through innovation, shining even more brightly in the field of plastic products and bringing people more beautiful and practical products.
