Most consumers will purchase silicone products because of their attractive color and appearance, especially in gifts and handicrafts. As we all know, silicone products belong to a type of rubber products that are both practical and aesthetically pleasing, and are widely used in daily life. In addition to their functional functions, the main reason why they can achieve multi-color effects and saturated color schemes is that they also invest a lot of time in adjusting the appearance color. Have you ever learned about how silicone product colors are obtained and what methods are used for adjusting them?
Firstly, it should be noted that the color pigment material of the color masterbatch is silicone material used for coloring. Various color additives are added to silicone material to achieve a certain color effect. Its chemical additives are mainly formulated for the raw materials of silicone products and cannot be used in other materials. Color blending can be used in any product without affecting it, such as daily silicone products, silicone decorative products, silicone gifts, and some electronic peripheral accessories.
What are the basic characteristics of silicone colorants?
1、 The Light Resistance of Silicone Color Masterbatch
The light resistance of silicone colorants refers to their ability to withstand light. Disperse the pigment in a certain medium to make a sample. At the same time, under a specified light source, after a certain period of exposure, compare the degree of color change and indicate the level 1 Z-difference and level 8 Z-bar.
2、 Heat resistance of silicone masterbatch
The heat resistance of silicone masterbatch refers to its ability to withstand heat, and the larger the number, the better the heat resistance. The pigment is dispersed in polyolefin to make one-third of the standard color, and after molding in an injection molding machine, it stays for 5 minutes.
3、 Migration resistance of silicone masterbatch
The migration resistance of silicone colorants refers to their ability to resist migration, which refers to the migration of colorants from the interior of a product to the surface of the product or from an interface between the product and the solvent.
In the production and processing of silicone colorants, the pigment is thoroughly mixed with the carrier through abundant mixing under the action of additives. When used, place a certain amount of colorants in the silicone gel to be processed, and the colorants quickly blend into the product. Compatibility is significantly better than coloring with color powder, so manufacturers of film and mold silicone products can better understand it. It is precisely because of the role of silicone colorants that silicone products can be blended to produce rich and colorful colors.
