Nano-manufacturer (aka. Technology Co. Ltd. has summarized Nano-silica’s specific applications after decades of exploring Nano-powders.
Plastic
Nano-silica Light-transmissive silica can be used to make plastics lighter. It also has smaller particle sizes, making them more malleable. Polystyrene films with silica can be improved in transparency, strength and toughness. They also have improved waterproofing and anti-aging performances.

Rubber
While rubber has excellent flexibility, it is not able to provide a complete performance. To increase the rubber’s strength, wear resistance and longevity, you will often need to use carbon black in rubber production. The grade of the rubber is low because the carbon makes it all black. China’s advent of nanoSiO2 has created a basis for new types of rubber products.
A small amount of nanoSiO2 was added to normal rubber. Its abrasion resistance and tensile strength are significantly improved. The color is also brightened and retains its color well.
Dye
While organic dyes can be brightly colored and offer strong color fidelity, they are less resistant to heat, light, solvent, migration and other environmental factors than inorganic. Surface modification of organic dyes with nano-SiO2 improves not only the anti-aging ability but also the brightness, hue, saturation.

Ceramics
Utilize nano-SiO2 Nano-additives that are not traditional can also be added to ceramics. They may play the role as Nano-particles and second-phase particle, which improve the strength and toughness of ceramic materials. It also increases hardness and elastic modulus. Nanoparticles are less effective than Nanoparticles.
additives.
Use of nano-SiO2 in the composite of ceramic substrates not only enhances density, toughness, smoothness, and sintering temp but it also significantly reduces them. The application of nano-SiO2 to ceramic products, such as ceramic filters or corundum ball is another important benefit.

Sealant Adhesive
It is important to have a variety of sealants and adhesives available. You need to provide the ideal conditions for product viscosity and fluidity as well as curing speed. Many foreign products have started to incorporate nano-materials in their modification. Nano-SiO2 has been the favorite material. The sealant is usually coated with organic material to hydrophobicize nano-SiO2. A silica structure quickly forms, which is when the nano-SiOX tiny particles create a network structure to slow down the curing process, inhibit colloids flow, increase the curing speed and enhance the bonding. Because of their tiny size, nano-SiO2 particle’s impermeability and sealing properties are enhanced.

Glass product
FRP products offer the benefits of lightweight, strength and resistance to corrosion, but they are also very hardy and don’t withstand wear. By ultrasonic dipersion, scientists add nanoSiO2 resin to gel coat resin and compare performance with gel coats without. nano-SiO2 The original Mohs hardness was 2.2. This is equal to the hardness for plaster. It has now increased to 2.82.9 Grade 3, which is level 3 of the hardness for natural marble. Nanoparticles made of organic polymers and organic polymers are more tough than the original 2.2. The material’s tensile and impact strengths have increased 1 times due to grafting or bonding. Also, heat resistance is greatly enhanced as we have already mentioned.
