Fumed Silica

We are manufacturing and exporting huge range of Fumed Silica from Chifeng, Nei Monggol, China. Known for their best quality.

Product name: SSAR150
CAS NO 112945-52-5
SYNONYMS: fumed silicon dioxide
Physical Description:
Fumed Silica is composed of submicron-sized spheres, which are 40-60% fused into short chains, very highly branched,0.1-0.2microns long. The spheres are quite uniform in size for a given product, but the chain lengths are quite variable,10 to 30 units in length. The surface area, which varies with the particle size, gives a good approximation if the sphere diameter. The smaller the particles, the larger the estimated surface area.
SSAR 150 is a hydrophilic fumed Silica with specific surface area of 150m2/g, and it synthetic, hydrophilic, amorphous silica, produced via flame hydrolysis. Particle between 7i 40nm.
Along with the traditional polyester, silicone, paints and coatings applications, hydrophilic SSAR products are used with increasing success in high technology fields. The particle nature and high purity of fumed silica play key roles in the electronics and optical fibers industries.
