First, the light resistance of silica gel masterbatch

The light resistance of silicone masterbatch refers to the ability of the masterbatch to withstand light. The pigment is dispersed in a certain medium, the sample is made, and the "sun fastness blue Standard" sample card is at the same time under the specified light source, after a certain time of exposure, the degree of discoloration is compared, and the expression is that grade 1 is the worst and grade 8 is the best.

Second, the heat resistance of silica gel masterbatch

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

Third, the migration resistance of silica gel masterbatch

The migration resistance of silica gel masterbatch refers to the ability of the masterbatch to withstand migration, and 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 the solvent.

In the process of production and processing of silica gel masterbatch, under the action of additives, the silica gel masterbatch is thoroughly connected with the carrier through abundant mixing. When used, it is placed in the silicone to be processed in a certain proportion, and the color master quickly enters the character and recognizes the "in-laws" with the silicone. Affinity - compatibility is significantly better than color powder color, therefore, on the production of film and silicone products manufacturers, more can be realized.

What should be considered in the purchase of silicone masterbatch? From the perspective of silicone products processing manufacturers - in order to produce general silica gel masterbatches, it is necessary to choose a high heat resistance grade and a wide range of pigments, and the pigment powder temperature resistance grade to a certain degree, every rise of 10 ° C ~ 20 ° C, the cost of pigments will rise by 50% ~ 100%.
