Products Description
As an environmentally friendly additive with excellent performance, silica is mainly used in rubber products (including
high-temperature vulcanized silicone rubber), ceramics, feed, paint/coatings, papermaking, pesticides,matting agent and other
fields.According to the production method, white carbon black is roughly divided into precipitated white carbon black and fumed
white carbon black.
Fumed white carbon black is white amorphous flocculent translucent solid colloidal nanoparticles (particle size less than 100nm)
under normal conditions, non-toxic, and has a huge specific surface area. Fumed silica is all nano-silica, the purity of the
product can reach 99%, and the particle size can reach 10-20nm, but the preparation process is complicated and the price is
expensive;
Precipitated silica is mainly used as a reinforcing agent for natural rubber and synthetic rubber, toothpaste friction agent, etc.
Fumed silica is mainly used as a reinforcing agent for silicone rubber, a thickener for coatings and unsaturated resins, and
ultrafine silica gel and aerogel are mainly used as matting agents for coatings, thickeners, and opening agents for plastic films.
