Yuan jiang card - precipitation ultra thin white carbon black Adopt high grade precipitated silica (silicon dioxide) as raw material, for ultrafine processing, make its reach micron particle size, close to the fumed silica in nature.With advanced equipment and technology, product extremely narrow particle size distribution.Uniform particle size, make this difficult to have high specific surface and excellent reinforcement and dispersion.Used in high temperature rubber, silicone rubber, to improve the tear strength.So, instead of fumed silica, and partly to reduce costs, is a better choice.
use
Yuan jiang card - is mainly used in silicone rubber, silicone rubber intermediates of precipitated silica rubber, plastic mold, glass, at the same time can also be applied to paint, ink, tires, sole, coatings, cosmetics, pesticide, textile and toothpaste, etc.
