    99.9% Undensified Silica Fume is a micro silica fume with 99.9% SIO₂ content, and the Bulk density is 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.

    99.9% Undensified Silica Fume Application:

    The characteristics of microsilica are mainly manifested in two aspects: volcanic ash activity and micro-particle nature.

    Therefore, microsilica is often used as a filler and modified additive.

    Used in high-performance concrete, it enhances concrete strength, improves performance, and extends concrete lifespan.

    Used in refractory materials, it enhances fluidity, reduces water usage, and improves product strength and durability.

    Used in dry mortar and grout, it increases early-stage strength.

    Used in wear-resistant flooring, it enhances flowability and increases abrasion resistance.

    Used in paints, coatings, resins, rubber, and other polymer materials as a filler.
