Do you know how the color of silicone products comes from?
Many consumers are attracted by the color and appearance of some products, especially in gifts and handicrafts. As we all know, silica gel products are a kind of rubber and plastic products that are internally practical and externally beautiful, and are widely used in life. In addition to its functional role, it can achieve multi-color effect and saturated color system, A lot of time is also invested in the deployment of appearance color. What are the detailed deployment processes?
First of all, we should know that the color pigment material of color masterbatch is silica gel material for coloring. Various color additives are added to silica gel material to achieve a certain color system effect. Its chemical additives are mainly prepared for the raw materials of silica gel products and cannot be used in other materials. The color deployment can be used in any products without impact, such as silica gel products for daily use, Silicone decoration products, silicone gifts and some electronic peripheral accessories, etc.
What are the basic characteristics of silica gel color masterbatch?
1、 Light resistance of silica gel color masterbatch
The light resistance of silica gel color masterbatch refers to the light resistance of color masterbatch. Disperse the pigment in a certain medium and make a sample. At the same time, compare the degree of discoloration with the sample card of blue standard for sun fastness under the specified light source and after exposure for a certain time. It shows that grade 1 is the worst and grade 8 is the best.
2、 Heat resistance of silica gel color masterbatch
The heat resistance of silica gel color masterbatch refers to the heat resistance of color masterbatch. The larger the number, the better the heat resistance. The pigment is dispersed in polyolefin to make one-third of the standard color and stay for 5min after molding in the injection molding machine.
3、 Migration resistance of silica gel color masterbatch
The migration resistance of silica gel color masterbatch refers to the ability of color masterbatch to resist migration. Migration refers to the migration of colorant from the interior of the product to the surface of the product or from a product to the product and solvent through the interface.
In the production and processing of silica gel color masterbatch, under the action of additives, silica gel color masterbatch is completely connected with the carrier through sufficient mixing. When in use, it is placed in the silica gel to be processed according to a certain share, and the color masterbatch quickly enters the character and recognizes "in laws" with the silica gel. Affinity - compatibility is significantly better than toner coloring. Therefore, manufacturers of film and silica gel products can experience it better.
What should be considered in the purchase of silica gel color masterbatch? From the perspective of silica gel product manufacturers - in order to produce general silica gel color masterbatch, it is necessary to select pigments with high heat resistance grade and wide application range. After the temperature resistance grade of pigment powder reaches a certain level, the cost of pigment will increase by 50% ~ 100% for every increase of 10 ℃ ~ 20 ℃.
