Silicon Dioxide SiO2 White Powder

Product name: Silica
Other name:white carbon black;Silicon dioxide

Application:
Rubber
Silica applied in tapes, rubber covered rollers, rubber tubes and rubber boards etc. can improve their wear resistance, and promote the wetting degree of rubber & fabric which contributes to rubber dispersion and penetration.
Tyre/Tire
Silica in tires can increase the wet skid & wear resistance and reduce the rolling resistance. It can improve the adhesion between rubber and steel-cord. Also it can promote the durability, flexing resistance and shock resistance of rubber.

Our quartz powder has high sphericity, uniform particle size, can be added in large quantities, and the viscosity of the polymer system does not change much;

The surface fluidity of nano quartz powder is good, and it is evenly mixed with resin to form a film. The amount of resin added is small, the fluidity is good, and the powder filling amount is high. The smaller the coefficient of thermal expansion, the lower the thermal conductivity, and the closer to the coefficient of thermal expansion of single crystal silicon, the better the performance of electronic components manufactured from it.

Paint and Coatings: Paint formulators select micron-sized industrial sands to improve the appearance and durability of architectural and industrial paint and coatings. High purity silica contributes critical performance properties such as brightness and reflectance, colour consistency, and oil absorption.

Glass making: Silica sand is the primary component of all types of standard and specialty glass. It provides the essential SiO2 component of glass formulation, and its chemical purity is the primary determinant of colour, clarity, and strength.

Metal Casting: Industrial sand is an essential part of the ferrous and non-ferrous foundry industry. Metal parts ranging from engine blocks to sink faucets are cast in a sand and clay mold to produce the external shape, with a resin bonded core creating the desired internal shape.

Metal Production: In metal production, silica sand operates as a flux to lower the melting point and viscosity of the slags to make them more reactive and efficient.

Chemical Production:Silicon-based chemicals are the foundation of thousands of everyday applications ranging from food processing to toothpaste, the silica is widely used in many areas.

Other Uasges: It is widely used in CCL, EMC, electronic adhesive, plastic, film, polishing, special ceramics, ink coating and cosmetics.
