Hydrophilic fumed silica
Product name:
SS®**0
CAS NO **********5
SYNONYMS: fumed silicon
dioxide
Physical Description:
Fumed Silica is composed of
submicron-sized spheres, which are ****0% fused into short chains,
very highly branched,0.**0.2microns long. The spheres are quite
uniform in size for a given product, but the chain lengths are
quite variable,*0 to *0 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.
SS® **0
is a hydrophilic fumed Silica with specific surface area of
**0m2/g, and it synthetic, hydrophilic, amorphous silica, produced
via flame hydrolysis. Particle between 7～*0nm.
Along with the traditional polyester, silicone,
paints and coatings applications, hydrophilic SS® **0
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.
