Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of Whole nano SiO2 silicon dioxide hydrophobic fumed silica silica nanoparticles

Our hydrophobic fumed silica nanoparticles (nano SiO2 silicon dioxide) are engineered for high-performance applications needing wetness resistance and enhanced material properties. The item contains pure silicon dioxide particles generated through a specialized fire hydrolysis process. This approach makes certain consistent bit size circulation, commonly ranging between 7-40 nanometers. The area is enhanced at 100-400 m ²/ g, offering solid communication with different matrices.

An essential feature is the hydrophobic surface treatment. This modification stops water absorption and improves compatibility with non-polar systems. The product remains secure in damp settings, preserving performance in time. Applications include finishings, adhesives, sealants, and compounds. In coverings, it minimizes resolving, boosts rheology, and increases weather condition resistance. For adhesives, it controls thickness and strengthens bond toughness.

The nanoparticles act as strengthening fillers in plastics and rubber, raising mechanical toughness without giving up versatility. They also serve as anti-caking agents in powders, making sure free-flowing homes. The chemical inertness of silica makes it ideal for usage in harsh problems, including direct exposure to acids, bases, and high temperatures approximately 600 ° C.

Handling is secure because of non-toxic composition, complying with international governing criteria. The item is supplied as a white powder with mass density in between 30-60 g/L. It integrates easily right into fluid or solid formulas through standard mixing procedures. Storage referrals include maintaining the material in a completely dry, trendy atmosphere to maintain its hydrophobic qualities.

Personalized options are offered for particle size, surface area, and hydrophobicity levels to satisfy particular commercial demands. Industries taking advantage of this product period vehicle, construction, electronics, and individual treatment. In cosmetics, it enhances texture and controls oil absorption. For electronics, it boosts insulation properties in encapsulants.

The material’s reduced dampness web content (much less than 1.5%) lessens clumping throughout processing. Its high purity (over 99.8%) guarantees consistent lead to critical applications. Compatibility with organic polymers and resins permits seamless integration right into existing manufacturing process.

5 FAQs of Whole nano SiO2 silicon dioxide hydrophobic fumed silica silica nanoparticles

Hydrophobic fumed silica nanoparticles are made of silicon dioxide (SiO2). The particles are extremely small, typically between 7-40 nanometers. They are processed to repel water, making them ideal for applications requiring moisture resistance. This material is created by treating fumed silica with silanes. The result is a powder that improves product performance in coatings, adhesives, and composites.

People often ask how hydrophobic fumed silica differs from regular silica. Regular silica absorbs water. Hydrophobic fumed silica resists water due to surface treatment. This treatment creates a non-polar layer. The layer stops moisture from interacting with the particles. This property makes it useful in environments where water exposure is a problem.

A common question is about applications. These nanoparticles are added to paints and coatings to prevent water damage. They thicken liquids without changing transparency. In adhesives, they reduce sagging and improve bonding. They are also used in cosmetics to adjust texture. Electronics manufacturers use them for insulation in sensitive components.

Safety is a priority. Hydrophobic fumed silica is generally safe when handled properly. Inhalation of dust can irritate lungs. Protective gear like masks and gloves is recommended. The material is chemically inert, so it doesn’t react with most substances. Users should follow safety guidelines provided by suppliers.

Storage conditions matter. Keep the powder in a dry, cool place. Moisture can clump the particles. Sealed containers prevent contamination. Avoid direct sunlight to maintain stability. Check the product’s shelf life before use. Proper storage ensures the material performs as expected.
