How are colorful silicone products made?

Everyone knows that silicone products are no longer as monotonous as before. Many accessories in the market, kitchen supplies in daily life, household items, and so on have different colors. However, many purchasing friends have doubts about the colorful silicone products, fearing that their color quality may have various problems. But for friends who are not very familiar with silicone products, do you know how silicone products are colored?

Silicone raw materials are originally transparent in color, colorless and odorless. They are a highly active material with strong adsorption properties and do not conflict with any substances except for strong alkalis. However, due to the need to maintain various styles of silicone raw materials during the production process, there are many choices available. Therefore, silicone product manufacturers use colorants to add various colors to it to maintain its appearance. Silicone colorants are formed by the aggregation of silicone raw materials, silicone oil, color powder, and dispersants. Therefore, choosing to use silicone colorants to produce the color of silicone products is because of their stable performance, high dispersibility, uniform use on products, environmental protection, non toxicity, non pollution, long-term storage, and will not expire. Many characteristics are similar to those of silicone raw materials. It can also be divided into many types, mainly organic colorants and inorganic colorants.

Silicone color masterbatch is an indispensable item for silicone product manufacturers. Its main process is used in the rubber mixing process. If no color masterbatch is added during the rubber mixing process, the mixed rubber will be transparent color. After molding and vulcanization, transparent silicone products will be obtained. The color of silicone masterbatch needs to be carefully adjusted to achieve good results, which is also an important technical task for silicone manufacturers. The color can reach thousands of different colors, and many products with little color difference are the most difficult to adjust. And when it is made with silicone raw materials, it is distributed according to the corresponding proportion and combined with vulcanizing agents to obtain the raw materials for making products. The performance selection of color masterbatch also affects the performance of a product. The common reason for color change in silicone products also has certain reasons in the selection of color masterbatch. The choice of light resistance performance, strong light resistance can achieve no color change effect, generally divided into eight levels! Heat resistance, the better its heat resistance, the higher its dispersibility. A high dispersibility means that the color distribution of the product is uniform, so it can be chosen in any way.
