Nano-manufacturer (aka. Technology Co. Ltd. summarized specific applications of Nanosilica after years exploring Nano-powders.
Plastic
Nano-silica Light-transmissive with a smaller particle size. This can make plastics dense. When silica is added to polystyrene, it improves the film’s transparency, strength and toughness, as well as its waterproofing and anti-aging capabilities.

Rubber
Rubber is a rubber elastomer that has excellent stretchability but its overall performance isn’t satisfactory. Carbon black is added to rubber to improve its strength, wear-resistance, and ageing resistance. Carbon black is added to rubber, but this results in a black product. The grade of the product is low. In China, nano-SiO2 is a new material that has enabled the production of a whole new generation of rubber goods with unique colors and high performance.
When rubber is treated with nano-SiO2, its abrasion and tensile resistance, flexibility and resistance to aging are all significantly enhanced. In addition, the color and color retention effects of the rubber is excellent.
Dye
Organic dyes may have vibrant colors and a high tinting power but they are not as resistant to light, heat, solvents, or migration than inorganics. Addition of nano-SiO2 to organic dyes improves their anti-aging and brightness properties.

Ceramics
Using nano-SiO2 Instead of adding traditional Nano-additives to ceramics, the particles can also be used as second-phase particles. This not only increases the strength and toughness but also increases the hardness and elastic modulus. The performance is better and the effect is more optimal than traditional Nano
additives.
By using nano-SiO2 in the composite of ceramic substrates, not only is the density, toughness and smoothness improved, but the sintering temp greatly reduced. The application of nano-SiO2 to ceramic products, such as ceramic filter and corundum ball is also very important.

Sealant Adhesive
Sealants, adhesives, and other important products are widely used and have many applications. This requires the right conditions in terms of product viscosity (liquidity), curing speed, and cure time. Nano-materials have been used as modifiers in many foreign products. Nano-SiO2 has become the most popular. It is mostly coated with a thin layer of organic material to make nano-SiO2 more hydrophobic, and then added to the sealant. It is formed quickly a silica-like structure, i.e., the Nano-SiOX small particles form a web structure that inhibits colloids from flowing, speeds up the curing, and enhances bonding. A small nano-SiO2 size increases both the sealing and the impermeability.

Glass Product
The FRP materials are light, have high strength and corrosion resistance but have low hardness. They also have poor wear resistance. Scientists use ultrasonic dispersion to add nano-SiO2 into the gelcoat resin. They then compare the performance of the gelcoat with and without the nano-SiO2. nano-SiO2 Wear resistance has been increased 1 to 2 fold by increasing the Mohs Hardness from 2.2 (equivalent of the hardness in plaster) to 2.82.9 grade 3 (level three is the hardness in natural marble). Nanoparticles are grafted and bonded to organic polymers, increasing the toughness and impact resistance of the material. Heat resistance is greatly improved as well, as mentioned above.
