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 fine white powder made by melting silicon tetrachloride in a flame of hydrogen and oxygen. This process develops bits with high area and strong thickening residential or commercial properties. The material is widely made use of in markets such as coverings, adhesives, and pharmaceuticals for its capacity to modify viscosity and enhance security.

The product looks like a cosy, agglomerated powder. It has a pureness level above 99.8%, making certain very little pollutants. The key bit dimension varies between 5 to 50 nanometers. These little fragments create a three-dimensional network, giving the material its thickening result. The surface area is typically 200 square meters per gram, determined making use of the BET technique. This high surface adds to its reactivity and efficiency in applications.

Fumed silica 200 is hydrophilic, indicating it brings in water. This property makes it ideal for water-based systems. The pH value in a 4% aqueous dispersion is around 3.5 to 5.5, suggesting minor acidity. The moisture material is much less than 1.5% when warmed at 105 ° C for 2 hours. Reduced dampness stops clumping and guarantees simple handling.

The mass thickness ranges from 30 to 60 grams per liter. This reduced thickness makes the powder light-weight and very easy to blend right into fluids. The product reveals superb resistance to heats, steady approximately 1,000 ° C. It likewise supplies UV resistance, making it valuable in finishings subjected to sunlight.

In rubber applications, fumed silica 200 boosts tensile stamina and abrasion resistance. In paints, it stops sagging and resolving of pigments. For adhesives, it regulates circulation and increases bond stamina. The powder is included during manufacturing, usually at 0.5% to 5% by weight, depending upon the wanted impact.

Handling calls for precautions. The great fragments can end up being air-borne, so make use of safety masks and air flow. Shop the product in a completely dry, amazing place far from dampness. Avoid straight call with skin or eyes. Adhere to neighborhood laws for disposal.

Fumed silica 200 is compatible with a lot of polymers and materials. It does not react with usual commercial chemicals under typical problems. Examinations verify it satisfies food-contact and medical-grade standards when processed correctly. Producers offer technological data sheets for particular guidance.

5 FAQs of fumed silica 200

What is fumed silica 200? Fumed silica 200 is a fine, white powder made from silicon dioxide. It is produced by burning silicon tetrachloride in a flame of hydrogen and oxygen. The result is a high-purity material with tiny particles and strong thickening properties. It is used to improve texture and stability in products like paints, adhesives, and coatings.

What industries use fumed silica 200? Many industries rely on this material. Paints and coatings use it to prevent sagging. Adhesives and sealants use it to control flow. In pharmaceuticals, it helps tablets hold their shape. Food products sometimes add it to keep powders from clumping. Its ability to thicken and stabilize makes it versatile.

Is fumed silica 200 safe? It is safe when handled properly. Direct contact with skin or eyes can cause irritation. Workers should wear gloves and goggles. Breathing in the dust may harm lungs. Masks and good ventilation reduce this risk. Follow safety guidelines from the supplier. Always check local regulations for proper handling.

How does fumed silica 200 differ from other silicas? Fumed silica 200 has smaller particles than precipitated silica. This gives it higher surface area and better performance in thickening.
