What are the basic functional characteristics of silicone rubber color masterbatch?

1、 Lightfastness of silicone rubber color master

The light fastness of silicone rubber masterbatch refers to its light fastness. Disperse the pigment in a certain medium to make a sample. At the same time, compare it with the sample card of the "light fastness blue standard" under the specified light source. After exposure for a certain time, compare the degree of color change, indicating that level 1 is poor, and level 8 is very good.

2、 Heat resistance of silicone rubber color master

The heat resistance of silicone rubber color masterbatch refers to the heat resistance of color masterbatch. The greater the digital economy, the better the heat resistance. The pigment can be dispersed in polyolefin to make a standard color of one third of the technology, and stay for 5min after molding in the injection molding machine.

Anti-migration of silicone rubber master batch

The migration resistance of silicone rubber masterbatch refers to the ability of the masterbatch to migrate from the inside of the product to the product surface or from the product to the product and solvent through the interface.

During the production and processing of silicone rubber masterbatch, the pigment is fully mixed with the carrier under the action of additives. When used, it is put into silicone rubber for processing according to a certain proportion.
