High purity 99.9% silicon oxide silica nanowires powder

Application of silica nanowires:

silica nanowires is an ultrafine powder having a particle diameter of less than 100 nm, usually 20-30 nm, high chemical purity, good dispersibility, and large specific surface area. In the chemical industry, also known as white carbon black, its products have been widely used in electronic packaging materials, polymer composites, plastics, coatings, rubber, pigments, ceramics, adhesives, glass steel, pharmaceutical carriers, cosmetics and antibacterial materials.

Specification of silica nanowires:

Average diameter:20-30nm, length>10um

Purity:99.9%

Note: We can supply different size products of silica nanowires according to client's requirements.

Product Performance

The microstructure of the silica nanowires is a floc and a network of nanowire structures. This special structure gives it a unique property: Silica nanowires have a UV reflectance of up to 70% to 80% for wavelengths up to 490 nm, which is added to polymer materials to achieve UV aging and heat aging. purpose. The small size effect of the silica nanowires and the macroscopic quantum tunneling effect cause the osmosis effect, which can penetrate into the vicinity of the unsaturated bonds of the polymer chain and interact with the electron cloud of the unsaturated bond to improve the heat of the polymer material. , light stability and chemical stability, thereby improving the product's aging resistance and chemical resistance. The silica nanowires have the characteristics of high strength, toughness and high stability at high temperature, and are dispersed in the material to form a three-dimensional network structure with the polymer chain, thereby improving the basic properties such as strength and elasticity of the material.

Storage conditions:
silica nanowires should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
