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 fumed silica 200

Fumed Silica 200 is a high-purity synthetic amorphous silicon dioxide. It is produced through a flame hydrolysis process. Silicon tetrachloride reacts with hydrogen and oxygen in a high-temperature flame. This creates tiny particles of silica. These particles form a three-dimensional chain-like structure. The result is a fine white powder with low bulk density. The material is known for its large surface area. Typical surface area ranges between 200 and 300 square meters per gram. Particle size is extremely small. Primary particles measure 5 to 50 nanometers. Aggregates form larger structures up to 200 nanometers.

Fumed Silica 200 is chemically inert. It does not react with most substances. It remains stable under high temperatures. The product withstands temperatures up to 1,200 degrees Celsius. Moisture content is very low. It is less than 1.5% when measured by loss on drying. The pH value is slightly acidic. It ranges between 3.7 and 4.5 in a 4% aqueous dispersion.

This material acts as a thickening agent. It improves viscosity in liquid systems. It prevents sagging in coatings and adhesives. It enhances the mechanical strength of rubber and plastics. It serves as an anti-settling agent in paints. It stabilizes free-flowing powders in food and pharmaceuticals. The product is hydrophobic. It repels water. This makes it ideal for applications requiring moisture resistance.

Fumed Silica 200 is used across industries. It is common in silicone rubber, sealants, and resins. It appears in personal care products like toothpaste and cosmetics. It functions as a rheology modifier in inks and coatings. It improves durability in composite materials.

Handling requires standard safety measures. Use gloves and goggles to avoid irritation. Store in a dry, cool place. Keep containers tightly sealed. Exposure to humidity can cause clumping. Do not inhale the powder. Use ventilation systems in workspaces.

The product meets international quality standards. It complies with FDA regulations for specific applications. Certificates of analysis are available upon request. Custom particle size and surface area options exist. Technical support is provided for formulation challenges.

Applications of fumed silica 200

Fumed silica 200 is a versatile material used in many industries. It is made by burning silicon tetrachloride in a flame. This process creates tiny particles with high surface area. The particles are lightweight and have strong thickening properties. These features make it valuable for improving product performance.

In coatings and paints, fumed silica 200 acts as a thickener. It stops liquids from dripping or sagging during application. It also boosts scratch resistance. This helps surfaces stay durable over time. The material works well in both water-based and solvent-based formulas.

Adhesives and sealants benefit from fumed silica 200. It adds strength and prevents settling of solid parts. This ensures consistency in products like industrial glues or construction sealants. The material improves adhesion and flexibility. This makes bonds last longer under stress or temperature changes.

Pharmaceuticals use fumed silica 200 as a flow agent. It helps powders mix evenly in tablets or capsules. The material does not react with active ingredients. This keeps medicines stable and effective. It is also used in gels and ointments to adjust texture.

Cosmetics rely on fumed silica 200 for smooth application. It absorbs oils and reduces shine in products like foundations or sunscreens. The fine particles give lotions a silky feel. They also prevent clumping in powders.

Rubber and plastics industries use fumed silica 200 as a reinforcing filler. It makes materials stronger without adding much weight. Tires, hoses, and silicone products gain better wear resistance. The material also improves heat stability in plastic parts.

Electronics applications include coatings for circuit boards. Fumed silica 200 protects components from moisture and dust. It enhances insulation in cables and connectors. The material’s purity ensures it does not interfere with electrical performance.

Fumed silica 200 is key in improving product quality across sectors. Its small particle size and reactivity allow precise adjustments in formulations. Manufacturers choose it for reliability and performance in demanding conditions.
