TJSW® MicroSilica (Silica Fume)
● Micro Silica , also called Silica Fume, it is byproduct of production silicon metal or ferrosilicon. It consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2), its average granule diameter is 0.10~0.20μm (micron), specific surface area is 15000~27000m2/kg, and it has extremely strong surface active.
● TJSW has been manufacturing and supplying micro silica since 2008. We provide different grades, densities and applications of micro silica that complies with ASTM C 1240, AS/NZS 3582.3:2016, EN13263:2005 and JIS A 6207: 2006 standards.
● Setting up our own collection systems at large-scale silicon metal and ferrosilicon factories to ensure the consistency and stability of quality. The recycle, densify and filling processes are automatically integrated in a closed environment without any mixture or impurities.
● 5000 m2 warehouse nearby Tianjin xingang and Shanghai port to ensures timely shipments and large amounts cargo shipments.
