New type of hydrophobic silica (white carbon black)

Thread Content

I recently came across a type of hydrophobic silica material (white carbon black), and after learning more about it, I found that this hydrophobic silica possesses some unique properties, so I’d like to share them with everyone here. It is a highly structured hydrophobic silica material suitable for silicone rubber applications. It is a hydrophobic powder that enables single-particle dispersion, and it can undergo thorough cross-linking reactions with silicone molecules ； A three-dimensional network structure is formed. Reduce the degree of structuring in silicone rubber. Its application in silicone rubber can better demonstrate its reinforcing and toughening properties, thereby improving the physical properties of silicone rubber such as temperature resistance, weather resistance, and UV resistance. The content of inorganic substances in silicone rubber is an important factor affecting its properties; the more inorganic substances there are, the more fully these properties can be expressed. The maximum addition level of this new type of silica in silicone rubber can reach 50%, without affecting the fluidity of the silicone rubber product; in other words, no thickening occurs after the product is formed. Because the monodisperse powder has excellent dispersibility, it is very convenient to add. Overall, hydrophobic, monodisperse, highly structured nano-white carbon black offers an excellent cost-performance ratio, representing a significant breakthrough for the silicone rubber industry.
