High quality precipitated white carbon black (silica) as raw materials for ultra-fine processing to achieve micron particle size, close to the fumed silica in nature. Due to the advanced equipment and technology, product particle size distribution is very narrow. Uniform particle size, so that the product has a high specific surface area and difficult to obtain good reinforcement and dispersion. For high-temperature plastic, silicone rubber, to improve their tear strength. So, can partially replace fumed silica, to reduce costs, it is a better choice.
Property:
The product is a particulate powder or granular amorphous, has a high insulation resistance, insoluble in water and ordinary acid, hydrofluoric acid and dissolved in caustic alkali, the high temperature is not biodegradable, water-absorbent, non-toxic.
