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 Fumed Silica HP-380 ( Chemical name : Silicon Dixocide )

Frequently Asked Questions About Fumed Silica HP-380

What is Fumed Silica HP-380?

Fumed Silica HP-380 is a high-purity form of silicon dioxide. It appears as a fine, white powder. This material is made through a flame hydrolysis process. It has a very small particle size and a large surface area. These features give it strong thickening and anti-settling abilities.

Where is HP-380 used?

HP-380 works well in many industrial products. You will find it in adhesives, sealants, paints, and coatings. It also goes into cosmetics, pharmaceuticals, and food-grade applications. Its main job is to control flow, prevent clumping, and keep solid particles evenly mixed.

Is HP-380 safe to handle?

Yes, but you must follow safety guidelines. Wear gloves, eye protection, and a dust mask when handling the powder. Avoid breathing in the dust. Store it in a dry place with the container tightly closed. Keep it away from moisture because it can absorb water from the air.

How much HP-380 should I add to my product?

The right amount depends on your specific formula. Most users add between 1% and 5% by weight. Start with a small test batch. Mix it slowly to avoid lumps. Adjust the amount based on the thickness or stability you need.
