The characteristics, scope of application and purchase instructions of silicone color masterbatches

Hits: 62 img

Silicone color masterbatch is used for the coloring of various silicone products. The silica gel masterbatch is made up of raw silica gel, various toners and various suitable additives.

The basic characteristics of silicone color masterbatch are as follows:

1. The light resistance of silica gel masterbatch
The light resistance of silicone color masterbatch refers to the light resistance of the color masterbatch. Disperse the pigment in a certain medium to prepare a sample. At the same time as the "Light Fastness Blue Standard" sample card, under the specified light source, after a certain period of exposure, compare the degree of discoloration, expressed by grade, Level 1 is the worst and level 8 is the best.

2. Heat resistance of silica gel masterbatch
The heat resistance of silicone masterbatch refers to the heat resistance of the masterbatch. The higher 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 silica gel 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 the colorant from the inside of the product to the surface of the product or from a product through the interface to the product and solvent.
    
Generally speaking, the scope of application of silicone color masterbatch includes:

Electronic product series: silicone keys, foot pads, mobile phone covers, computer keyboard covers, etc.

Miscellaneous parts: sealing rings, sealing strips, car reducers, trademarks, ashtrays, etc.
Cable: high temperature wire.

In the production and processing of silica gel masterbatch, the pigment is fully mixed with the carrier under the action of additives. In use, put a certain amount in the silica gel to be processed, the color masterbatch quickly enters the character, and the silica gel is recognized as "in-law". Affinity—Compatibility is significantly better than toner coloring. Therefore, manufacturers who produce film and silicone products can appreciate it better.

What should be considered when purchasing silicone color masterbatch? Let us speak from the manufacturer's point of view-in order to produce general-purpose silicone color masterbatches, it is necessary to select pigments with a higher heat resistance grade and a wide range of applications. When the temperature resistance grade of the pigment powder reaches a certain level, it will increase by 10℃~20℃ every time. , The cost of pigments will increase by 50% to 100%
