White carbon black can be seen everywhere in our daily life. Let's see where white carbon black is applied:


1. In the silicone rubber, silica will react in the silicone rubber. For general silicone rubber, ordinary ultra-fine silicon rubber is required. For high-quality silicone rubber, low iron (yellow and red when iron is high) products are required. Low-iron products with high oil absorption value and large specific surface area are the best choice, which can better react with silicone rubber raw materials.


2. For plastic and plastic products, it is better to need products with large specific surface area and high oil absorption value, and it is better to modify them, so that the products obtained are wear-resistant, aging resistant, transparent, and maintain the original color of pigments.


3. For hard rubber cushion block, silica needs low surface area and low oil absorption value.


4. For the toothpaste friction agent, ultra-fine products with low specific surface area and low oil absorption value are required; For toothpaste thickener, it needs high specific surface oil absorption value. Some people take the intermediate products of the two as a mixed additive, which is not advisable.


5. For water-absorbing silica, such as diaper, products with high oil absorption value are required, which can better absorb urine and replace water-absorbing resin. During use, the air in the white carbon black gas powder should be extracted to make the volume compressed.
