Do you know how the rich and colorful colors of silicone products come about?

Many consumers are attracted by the color and appearance of certain products, especially in gifts and handicrafts. As is well known, silicone products belong to the category of rubber and plastic products that are both practical and beautiful. They are also widely used in daily life. In addition to their functional role, the reason why they can achieve a multi-color effect and saturated color system is mainly because they have invested a lot of time in adjusting the appearance color. So, what are the detailed methods for adjusting?

Firstly, it is important to know that the color pigment material of the color masterbatch is silicone material used for coloring. Various color additives are added to the 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 mixing can be used in any product without affecting it, such as household silicone products, silicone decorative products, silicone gifts, and some electronic peripheral accessories, etc.

What are the basic characteristics of silicone masterbatch?

1、 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 form one-third of the standard color, and stays for 5 minutes after molding in an injection molding machine.

2、 Light resistance of silicone masterbatch

The light resistance of silicone masterbatch refers to its ability to withstand light. Disperse the pigment in a certain medium and make a sample. At the same time as the "Blue Standard for Sun Fastness" sample card, expose it to a specified light source for a certain period of time. Compare the degree of color change and indicate that level 1 is the worst and level 8 is the best.

3、 Migration resistance of silicone colorants

The migration resistance of silicone masterbatch refers to the ability of masterbatch to migrate. Migration refers to the migration of colorants from the interior of a product to the surface of the product or from an interface of a product to the product and solvent.

In the production and processing of silicone masterbatch, the pigment is thoroughly connected with the carrier through abundant mixing under the action of additives. When in use, it is placed in a certain proportion of the silicone to be processed, and the color masterbatch quickly enters the human body. It is recognized as "in laws" with the silicone, and its affinity and compatibility are significantly better than those of color powder coloring. Therefore, for manufacturers of film and silicone products, it is more noticeable.

What should be considered when choosing silicone masterbatch? From the perspective of silicone product processing manufacturers, it is necessary to choose pigments with high heat resistance and wide applicability in order to produce universal silicone masterbatch. After the temperature resistance level of pigment powder reaches a certain level, the cost of pigments will increase by 50% to 100% for every 10 ℃ to 20 ℃ increase.
