Introduction:

90% Densified Silica Fume is a micro silica fume with 90% SIO₂ content, and the Bulk density is 240-320kg/m³.

Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. It consists primarily of amorphous silicon dioxide (SIO₂), its average granule diameter is 0.15~0.20 μm, specific surface area is 15000~20000 m²/kg. Mainly used for high transparency, high resistance to tear silicone rubber, silicone grease, sealed packaging materials such as capacitors.

Ewende strictly follows the ISO9001:2008 quality management system, conducts strict screening of raw materials and strengthens regular follow-up inspection of materials and machinery to ensure that we can provide customers with high quality silica fume products. independent experiments, and can meet the different needs of different customers in different industries.
