Product Details

【Product Introduction】

The product is made from renewable resources such as rice husk and straw using the carbon dioxide acidification process to produce bio-based silica for silicone rubber ( bio-based silica also known as bio-based white carbon black / rice husk silica / rice husk white carbon black). It is a white, non-toxic, amorphous micro pearl substance. The product is an important inorganic silicon compound with excellent properties such as porosity, easy dispersion, light weight, good chemical stability, high temperature resistance, non-combustion, and good electrical insulation.

【Application scope】

The bio-based silica is specially treated and is mainly used as a reinforcing agent in silicone rubber products. The product can be used as a carrier in special applications and as a reinforcing filler in silicone rubber applications such as HTV, LSR and RTV-2C to improve mechanical strength and stabilize viscosity. It can control the rheology and thixotropy of liquid systems, adhesives, polymers, etc., and is used for anti-settling and thickening.
