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 the NS series of 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 can be widely used as a rubber reinforcing agent. It is used in rubber products such as automobile tires, soles, tapes, rubber sheets, rubber tubes, hot water bottles, rubber rollers, and wear-resistant parts. This product can be used for soles, all-steel and semi-steel radial tires, and can be filled with 10-80 parts.
