Ultrafine silica is a common high-performance industrial material, also known as nano-silicon dioxide, Silica, ultrafine white carbon black, submicron carbon black or ultrafine fly ash. It is a product obtained after the pyrolysis of homogeneous carbon polymer or vapor deposition carbonized material. The particle diameter of ultrafine silica is usually less than 100 nanometers, has a high specific surface area and adsorption capacity, and is mainly used to enhance the performance of materials and improve the texture of products.

According to current scientific research, ultrafine silica is relatively safe under normal use conditions and has no obvious toxicity.

At present, ultrafine silica is mainly used in coatings, plastics and rubber industries, road construction, and other environmental protection fields. It can be used with confidence, safe and non-toxic.

However, because ultrafine silica is a nano-level substance, long-term exposure to high concentrations of ultrafine silica dust may cause irritation and damage to the respiratory system. Therefore, when using ultrafine silica during the production process, it is recommended that workers take appropriate protective measures, such as wearing masks and maintaining a well-ventilated working environment, to reduce potential health risks.
