Hydrophobic and Hydrophilic Silica Aerogel Powder

Product introduction of Silica Aerogel Powder

As the lightest solid in the world, aerogel is a porous solid material whose dispersion medium is gas. The density of this new material is only 3.55kg/m3, which is only 2.75 times the density of air. The porosity is as high as 80-99.8%, the typical size of the pores is 1-100 nm, and the specific surface area(SSA) is 200-1000 m2/g.

Silica aerogel is sometimes called "solid smoke" or "frozen smoke" because of its translucent color and ultra-light weight. This new material looks fragile, but it is actually very durable and can withstand temperatures of up to 1,400℃.High porosity, high transmittance, low thermal conductivity and low density are its typical characteristics can be developed into many application products and the derived products have been widely used in many fields. Silica aerogel powder can be directly filled, and can also be made into thermal insulation felt, board, block, coating and adsorbent etc.

Physical and Chemical Indicators of Silica Aerogel Powder

Advantages of Silica Aerogel Powder

1.Thermal insulation, room temperature thermal conductivity is 0.018W/(m·K), and thermal insulation performance is 3 to 5 times that of traditional thermal insulation materials.

It is fireproof and hydrophobic, and can reach the national A-level non-combustible standard for building materials, and the hydrophobicity rate is ≥99%.

2.Lightweight and high strength, the product density is about 200kg/m3, with good flexibility and tensile strength.

3.Long-lasting weather resistance, the aerogel insulation material is hydrophobic as a whole, not easy to disintegrate and settle, and the service life can reach more than 10 years, which is 3 to 5 times longer than that of traditional insulation materials.

4.The construction is convenient and can be processed into the required shape suitable for complex parts by using ordinary cutting tools.

5.Safe anti-corrosion, aerogel can effectively prevent the penetration of liquid water, and can effectively prevent corrosion under the insulation layer.

6.Healthy and environmentally friendly, the products have passed RoHS testing and contain no harmful substances.

Packaging and Storage of Silica Aerogel Powder

Cardboard drum packaging: 5kg/bag

The powder has a certain degree of moisture return, should be sealed and stored, and keep the surrounding environment dry and ventilated. Do not exceed 40 ℃, do not oversize.
