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.

Secret Makes Use Of Across Industries

This hydrophobic fumed silica powder is made in controlled manufacturing facility problems. It brings CAS number 112945-52-5 and comes with a minimum order of 1 kg. The powder repels water well due to the fact that it has actually been treated with organic teams. This makes it really beneficial in lots of products where moisture resistance matters.

Paints and Coatings
Include this silica to paints and industrial coatings. It quits fluids from taking in. It also helps keep the surface smooth and free from drooping or leaking during application.

Adhesives and Sealers
In adhesives and sealers, the powder works as a thickener. It provides better control over flow and protects against splitting up of active ingredients. The last bond remains strong even in humid problems.

Plastics and Rubber
Makers blend it right into plastics and rubber substances. It enhances strength and keeps the product secure in time. Water can not easily enter, so the item lasts longer outdoors or in wet areas.

Cosmetics
Charm products like powders and foundations use this silica too. It feels light on the skin and takes in oil without caking. It also aids other active ingredients stay equally blended.

Industrial Lubricants
When contributed to oils and oils, it stops them from dripping or weakening at heats. The silica holds everything with each other while still letting the lubricant do its work.

This hydrophobic fumed silica is simple to deal with and mixes well into different systems. Its consistent high quality makes it trusted for large-scale manufacturing. Manufacturing facilities pick it since it executes the same way each time.
