The wonderful use of silica and its influence on the properties of vulcanizate



We white carbon black manufacturers have said a lot about white carbon black before. Today, we are talking about the wonderful use of white carbon black and its impact on the properties of vulcanizates.


White carbon black is the general name of white powdery X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica, ultrafine silica gel and aeronenenebb gel, and also including powdery synthetic aluminum silicate and calcium silicate.


1. White carbon black is used in colored rubber products to replace carbon black for reinforcement and meet the needs of white or translucent products.


2. In agricultural chemicals, such as pesticides and high-efficiency spraying fertilizers, white carbon black can be used as a carrier or diluent to maintain long-lasting effectiveness.


3. Transparent color and opaque toothpaste with white carbon black as filler and abrasives have good flexibility and dispersion. The paste is soft and has good abrasivity, and does not abrade the toothpaste tube; It can stabilize the drug properties of medicated toothpaste.


4. Used in adhesives made of natural rubber or synthetic rubber, it provides thixotropy and reinforcement.


5. Using white carbon black as paper filler can improve the ink penetration resistance and mechanical strength of paper, increase whiteness and reduce unit weight.


Our white carbon black manufacturer will tell you about its impact on the properties of vulcanizates:


Silica has a very significant reinforcing effect on various rubbers, especially on silicone rubber. White carbon black is a kind of white reinforcing agent whose reinforcing effect is second only to that of corresponding furnace carbon black. Compared with vulcanizates reinforced by corresponding furnace carbon black (such as HAF), vulcanizates containing a certain amount of white carbon black have the advantages of high strength, large elongation, high tear strength, high hardness and good insulation. Carbon black and white carbon black are usually used together to obtain better comprehensive properties.
