Basic Info

Product Description

Product name:White Carbon Black (Silica)Silica is divided into gas phase silica and precipitated silica. The finer the gas phase silica particles are, the larger the specific surface area is, the better the reinforcing effect is, but the worse the operation performance is. On the contrary, its particles are thicker, the specific surface area is small, the reinforcing effect is poor, but the operation is better. Gas phase silica is one of the commonly used reinforcing agents for silicone rubber. The rubber reinforced by it has high mechanical strength and good electrical properties. The properties of precipitated silica are affected by precipitation conditions such as acidity and temperature. Precipitated silica has better heat aging performance, and the cost of mixing rubber is much lower. When the mechanical strength of the product is not high, you can precipitate silica or make it and gas phase silica .
