Many consumers are attracted by the color and appearance of some products, especially in gifts and handicrafts. As we all know, silicone products are a kind of rubber and plastic products that are practical and beautiful, and are used in life. It is also relatively extensive. In addition to its functional role, the reason why it can achieve multi-color effects and saturated color systems is that a lot of time has been invested in the appearance of colors. Woolen cloth?

First of all, it is necessary to know that the color pigment material of the masterbatch is the silica gel material for coloring. Various color additives are added to the silica gel material to achieve a certain color effect. Its compounding additives are mainly formulated for the raw materials of silica gel products, and cannot be used. Among other materials, color matching can be used in any product without any impact, such as living silicone products, silicone decorative products, silicone gifts, and some electronic peripheral accessories.

What are the basic characteristics of silicone masterbatch?

1. The light resistance of silicone color masterbatch

The light resistance of silicone color masterbatch refers to the ability of the color masterbatch to withstand light. Disperse the pigment in a certain medium to make a sample, and compare the degree of discoloration after exposure to the sun for a certain period of time with the sample card of "Blue Standard for Light Fastness" at the same time, and express, 1 Grade 8 is the worst, and Grade 8 is the best.

2. Heat resistance of silicone color masterbatch

The heat resistance of the silicone color masterbatch refers to the ability of the color masterbatch to withstand heat. The larger the number, the better the heat resistance. The pigment is dispersed in polyolefin to make one-third of the standard color, and it stays for 5 minutes after molding in the injection molding machine.

3. Migration resistance of silicone color masterbatch

The migration resistance of silica gel masterbatch refers to the ability of the color masterbatch to resist migration. Migration refers to the migration of colorants from the inside of the product to the surface of the product or from a product through the interface to the product and the solvent.

During the production and processing of silica gel masterbatch, under the action of additives, the silica gel color masterbatch is thoroughly connected with the carrier through sufficient mixing. When using, it is placed in the silica gel to be processed according to a certain proportion, and the color masterbatch quickly enters the character and identifies with the silica gel as "in-law". Affinity - Compatibility is significantly better than toner coloring, so it is better for manufacturers of films and silicone products.

What should be considered in the purchase of silicone masterbatch? From the perspective of silicone product processing manufacturers - in order to produce general-purpose silicone masterbatches, it is necessary to use pigments with higher heat resistance levels and a wide range of applications, and after the temperature resistance level of pigment powders reaches a certain level, the temperature rises by 10 ℃ ~ 20 ℃, the cost of pigments will increase by 50% to 100%.
