Product Summary
Hydrophilic Fumed Silica 200 is a premium-grade nano silica powder made through pyrogenic synthesis. It brings the CAS number 7631-86-9 and matches the performance of typical fumed silica grades utilized across several industries. This white, free-flowing powder attributes ultrafine bits with high surface, offering superb thickening, anti-settling, and reinforcing residential or commercial properties.
Secret Qualities
The product is hydrophilic , indicating it readily absorbs dampness from the air and spreads well in water-based systems. Its key bit size ranges between 7– 40 nanometers , while the specific area is about 200 m TWO/ g (wager method). The silica content goes beyond 99.8%, ensuring very little contaminations. It is safe, chemically inert under typical problems, and thermally secure up to 1000 ° C .
Typical Applications
This fumed silica functions efficiently as a rheology modifier in paints, layers, adhesives, and sealants. It prevents pigment settling and enhances suspension stability. In cosmetics, it serves as a free-flow agent and mattifying ingredient. Rubber and silicone manufacturers utilize it to boost tensile toughness and tear resistance. It also functions as a service provider or anti-caking representative in food-grade and pharmaceutical powders when certified grades are chosen.
Handling and Storage space
Shop the item in a completely dry, awesome place inside sealed containers. Because it is hydrophilic, exposure to moisture might create clumping. Usage conventional commercial health methods during handling– put on gloves and eye defense. Prevent developing dust clouds; usage local exhaust ventilation where needed. Keep away from strong acids or bases to keep item honesty.
Technical Conformity
This silica fulfills global high quality criteria for pyrogenic silica. Batch-specific certificates of analysis are offered upon request, consisting of information on loss on drying out, pH worth (in diffusion), and heavy metal limits.

Applications of Hydrophilic Fumed Silica 200 (CAS 7631-86-9)
Thickening and Anti-Settling Agent
Hydrophilic fumed silica 200 works well as a thickener in fluids. It stops solid particles from sinking to the bottom. Paints, finishings, and adhesives stay stable over time because of this. The powder mixes conveniently right into water-based systems and offers constant structure without clumping.
Rheology Control in Industrial Formulations
This nano silica powder regulates just how liquids circulation. In sealers and caulks, it aids maintain form after application. The material does not run or trickle. That makes it less complicated for workers to use evenly. It additionally enhances droop resistance on vertical surfaces.
Support in Silicone Rubbers
Makers include fumed silica 200 to silicone rubber to make it stronger. The small particles fill up gaps in between polymer chains. This improves tensile stamina and tear resistance. Products like gaskets, medical tubing, and key-board pads last longer with this additive.
Free-Flow Representative for Powders
Dry powders typically stick or absorb wetness. Adding a small amount of hydrophilic fumed silica maintains them moving freely. It is common in food powders, pharmaceuticals, and cosmetics. The powder stays simple to put and gauge precisely.
Matting Representative in Coatings
For a soft, non-shiny finish, this silica lowers surface gloss. It spreads light equally across repainted surface areas. Furniture finishes, automotive finishes, and commercial paints use it to achieve a consistent matte look without shedding sturdiness.
Stabilizer in Adhesives and Inks
In printing inks and adhesive solutions, CAS 7631-86-9 fumed silica stops separation. Pigments and materials stay blended throughout storage. The end product applies smoothly and dries out with regular color and bond toughness.

5 FAQs of 7631-86-9 7631-86-9 Pyrogenic Silica Equivalent Nano Silica Powder Hydrophilic Fumed Silica 200 With CAS 7631-86-9
Frequently Asked Questions About Hydrophilic Fumed Silica (CAS 7631-86-9)
What is hydrophilic fumed silica?
Hydrophilic fumed silica is a very fine powder made from silicon dioxide (SiO₂). It has the CAS number 7631-86-9. This material is created through a high-temperature process called pyrogenic synthesis. The result is nano-sized particles that easily mix with water and polar liquids.
What does “hydrophilic” mean in this context?
“Hydrophilic” means the silica attracts and bonds well with water. Unlike hydrophobic types, this version does not need surface treatment. It naturally disperses in water-based systems. That makes it useful in many liquid formulations.
What are common uses for this silica?
This silica works as a thickener, anti-settling agent, and flow controller. You will find it in paints, adhesives, cosmetics, pharmaceuticals, and food products. It helps keep solid particles suspended and stops liquids from separating.
Is this product safe to handle?
Yes, but you must follow basic safety steps. Wear gloves and a mask when handling the dry powder. Avoid breathing in the dust. Store it in a dry place away from moisture. Always check the safety data sheet before use.
How is this different from other silica powders?
This type is made by flame pyrolysis, which gives it high purity and consistent particle size. Its surface has silanol groups that make it water-friendly. Other silica types may be ground quartz or precipitated silica, which have different structures and performance traits. This fumed silica offers better thickening power at low doses.
