Specification of Popular Fumed Silicon Dioxide Colloidal Nano Silica Hydrophobic Hydrophilic SiO2 Fumed Silica

Fumed silicon dioxide, known as colloidal nano silica or fumed silica, is a fine powder made by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates tiny particles with high purity. The particles are extremely small, typically between 5 and 50 nanometers. These particles form three-dimensional networks, giving the material unique properties. The product comes in two types: hydrophobic and hydrophilic. Hydrophobic fumed silica repels water. It is treated with silane agents to achieve this. Hydrophilic fumed silica attracts water. It has hydroxyl groups on its surface, making it mix easily with polar liquids.

The material has a high surface area, ranging from 50 to 400 square meters per gram. This large surface area improves thickening, thickening, and reinforcement in various applications. It is chemically inert. It does not react with most substances. It works well in solvents, polymers, and resins. The powder has low bulk density. It appears fluffy and lightweight. It absorbs liquids effectively, preventing clumping in powders.

Fumed silica is used in many industries. In coatings and paints, it acts as a rheology modifier. It controls flow, prevents sagging, and improves finish durability. In adhesives and sealants, it enhances strength and resistance to temperature changes. The pharmaceutical industry uses it to stabilize tablets and control drug release. In cosmetics, it thickens creams, reduces shine, and improves texture. The food industry applies it as an anti-caking agent in powders like spices or coffee creamer.

Hydrophobic fumed silica is ideal for waterproofing applications. It is added to silicone rubber, coatings, and gels to repel moisture. Hydrophilic types are common in water-based systems. They improve viscosity and stability in products like inks or detergents. Both types meet strict safety standards. They are non-toxic and safe for industrial use. Proper handling is necessary to avoid dust inhalation.

The product is packaged in moisture-proof bags or containers. Common sizes include 10-kilogram bags, 20-kilogram paper drums, or bulk orders. Storage recommendations include keeping it dry and cool. Shelf life is typically two years when stored correctly. Custom particle sizes and surface areas are available for specific needs.

5 FAQs of Popular Fumed Silicon Dioxide Colloidal Nano Silica Hydrophobic Hydrophilic SiO2 Fumed Silica

Fumed silicon dioxide, often called fumed silica, is a fine white powder made by burning silicon tetrachloride in a flame of hydrogen and oxygen. The process creates tiny particles with high surface area. This material is used as a thickener, anti-caking agent, or stabilizer in products like paints, adhesives, cosmetics, and food. It comes in two types: hydrophobic (water-repelling) and hydrophilic (water-attracting). Both types improve texture, prevent clumping, and boost performance in industrial applications.

What is the difference between hydrophobic and hydrophilic fumed silica? Hydrophobic fumed silica is treated to repel water. It works well in waterproof coatings, silicone rubber, or products needing moisture resistance. Hydrophilic fumed silica absorbs water easily. It suits applications like adhesives, pharmaceuticals, or products requiring water interaction. The choice depends on whether the product needs to block or mix with water.

Why use fumed silica in industrial applications? Fumed silica adds strength to materials. It controls viscosity, stops settling, and improves durability. In paints, it prevents dripping. In sealants, it adds flexibility. In cosmetics, it gives a smooth texture. The nanoparticles fill gaps between larger particles, creating a stable structure. This makes products last longer and perform better.

Is fumed silica safe? Fumed silica is generally safe when handled properly. Inhalation of dust can irritate lungs. Use masks and ventilation. Skin contact is low-risk but gloves are recommended. In food-grade products, it meets safety standards. It is non-toxic but not digestible. Always check regulations for specific uses. Unlike crystalline silica, fumed silica does not cause silicosis. Still, follow safety guidelines.

How to choose between hydrophobic and hydrophilic fumed silica? Consider the product’s interaction with water. Hydrophobic is best for water resistance. Examples include outdoor coatings or rubber parts exposed to rain. Hydrophilic works for water-based systems. Examples include liquid detergents or drug tablets. Test both types for compatibility. Particle size and surface treatment affect performance. Suppliers provide technical data to help decide.
