Application

Rubber modification, sealant ceramic toughening, binder modification, functional fiber additives, plastic modification, anti paint aging additives; Ceramic, nano ceramic, composite ceramic substrates; Polymer: it can increase the thermal stability and aging resistance of polymer; Flame retardant materials, coatings, grinding media, cosmetics and other products;

Enhance the toughness, strength, elongation, bending resistance, UV aging and thermal aging properties of rubber products; The problems of poor suspension stability, poor thixotropy, poor aging resistance and low smoothness are well solved by adding a small amount of nano silica to the traditional coatings.

Nano silica can be applied to cement-based pavement materials, by adding a certain amount of nano silica to replace a portion of ordinary concrete aggregates, thereby improving the performance of concrete.
