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.

5 FAQs of nano hydrophobic fumed silica sio2 treated fumed silicon dioxide HB-615 white carbon black powder factory

What is nano hydrophobic fumed silica HB-615?
Nano hydrophobic fumed silica HB-615 is a high-purity, ultra-fine white powder made of fumed silicon dioxide (SiO₂) treated with organosilane compounds. This treatment creates a water-repellent surface, making it hydrophobic. It’s also known as “white carbon black” due to its reinforcing and thickening properties. The material features low moisture absorption, high dispersibility, and thermal stability, ideal for applications requiring moisture resistance and enhanced performance.

What are the primary applications of HB-615?
HB-615 is widely used in coatings, adhesives, sealants, and elastomers (CASE) to improve rheology, anti-settling, and thixotropy. It’s added to plastics, resins, and composites for reinforcement and reduced viscosity. In cosmetics, it enhances texture and stability in sunscreens or creams. It’s also used in pharmaceuticals, inks, and electronic encapsulants to provide water resistance, flow control, and durability in harsh environments.

How does hydrophobic treatment benefit HB-615 compared to untreated fumed silica?
The hydrophobic treatment reduces surface hydroxyl groups, minimizing moisture absorption and improving compatibility with non-polar matrices like polymers or oils. This prevents clumping in humid conditions, enhances dispersion in organic systems, and ensures consistent performance. Untreated hydrophilic silica absorbs water, leading to aggregation and reduced effectiveness in moisture-sensitive applications.

Is HB-615 safe to handle?
HB-615 is generally safe but requires precautions due to its nano-scale particles. Use PPE (gloves, masks, goggles) to avoid inhalation or skin contact. Ensure proper ventilation in processing areas. It’s non-toxic but can cause irritation if mishandled. Follow SDS guidelines for storage (cool, dry place) and disposal. Regulatory compliance (e.g., REACH, OSHA) must be verified based on regional standards.

What technical specifications define HB-615 quality?
Key specs include BET surface area (100–160 m²/g), average particle size (7–40 nm), pH (5.5–7.5), and loss on drying (≤1.5%). Hydrophobicity is measured by methanol wettability (≥50%). Purity exceeds 99.8% SiO₂, with trace metals 500 ppm. Customizable parameters like particle size distribution or surface treatment intensity are available to meet specific industrial requirements. Quality control includes ISO-certified testing for consistency.
