Description
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.

High-Purity Fumed Silica– CAS 112945-52-5
Product Summary
This item is amorphous fumed silica (SiO ₂), also called pyrogenic silica. It appears as a penalty, free-flowing white powder. The material satisfies rigorous industrial standards and carries the CAS number 112945-52-5. It is not rice flour– it is a high-performance industrial additive commonly made use of for thickening, anti-caking, and reinforcement.
Trick Residences
Purity: Over 99.8% SiO ₂.
Surface: 50– 400 m ²/ g (BET method).
Mass thickness: 30– 80 g/L.
Loss on drying: ≤ 1.5% at 105 ° C for 2 hours.
pH worth: 3.5– 4.5 in 4% liquid dispersion.
The bits are nano-sized and kind branched, chain-like aggregates. This framework offers the silica strong thickening power also at low dosages. It distributes well in liquids and continues to be secure under normal storage problems.
Common Applications
Fumed silica is used across lots of sectors:.
– In paints and finishes to prevent pigment settling and control flow.
– In adhesives and sealants to change thickness and stop drooping.
– In cosmetics as a free-flow agent and structure enhancer.
– In food-grade products (when licensed) to maintain powders dry and different.
– In rubber and plastics to enhance stamina and resilience.
Handling and Storage
Shop in a great, completely dry location far from dampness. Maintain containers firmly shut. Usage basic industrial health practices– use handwear covers and eye security when handling huge amounts. Avoid breathing dirt. The item is safe but might create mild inflammation if breathed in or exposured to eyes.
Quality control
Every set undertakes strenuous testing for purity, fragment size, and efficiency. Full paperwork– consisting of certificates of evaluation and safety and security information sheets– is available upon demand. Our fumed silica complies with global regulative demands for commercial usage.

Applications of Fumed Silica (CAS 112945-52-5)
Enlarging and Anti-Settling Representative
Fumed silica is extensively made use of to manage the flow of liquids. It helps stop strong bits from sinking in paints, finishes, and adhesives. This keeps the item secure throughout storage space and makes it much easier to use.
Reinforcement in Rubber and Plastics
In rubber products like tires or seals, fumed silica boosts toughness and put on resistance. It also enhances just how plastics manage stress and anxiety and heat. This leads to longer-lasting industrial parts.
Free-Flow Help in Powders
Numerous powdered materials tend to glob with each other, especially in moist conditions. Adding a percentage of fumed silica maintains powders moving smoothly. This is very important for food-grade additives, pharmaceuticals, and commercial white rice flour blends.
Matting Agent in Coatings
Fumed silica provides surfaces a soft, non-reflective finish. Paints and varnishes use it to create matte results without losing longevity. The outcome is a clean look that stands up to scrapes and fingerprints.
Efficiency Booster in Adhesives and Sealants
When mixed into adhesives or sealants, fumed silica stops them from leaking or drooping on vertical surfaces. It likewise helps keep constant texture and bonding power gradually.
Usage in Cosmetics and Personal Treatment
Due to the fact that it is pure and great, fumed silica works well in makeup, creams, and deodorants. It takes in oil, enhances spreadability, and offers products a silky feel.
Specialized Applications
Fumed silica contributes in state-of-the-art fields also. It shows up in battery elements, thermal insulation, and even customs protection inks where specific bit habits matters. Its ultra-fine structure and high surface make it excellent for sensitive formulas.

5 FAQs of Customs security/amorphous fumed silica/SiO2 silica/industrial white rice flour cas112945-52-5/fumed silica
Common Questions About Fumed Silica (CAS 112945-52-5)
What is fumed silica?
Fumed silica is a very fine white powder made from silicon dioxide (SiO₂). It is produced by burning silicon tetrachloride in a flame. This creates tiny particles that clump together. The result is a lightweight, fluffy material used in many industries.
Why is it called “amorphous” fumed silica?
“Amorphous” means the material has no regular crystal structure. Unlike quartz or sand, which are crystalline forms of silica, fumed silica’s atoms are arranged randomly. This makes it safer to handle and more useful in products like paints, adhesives, and cosmetics.
Is fumed silica the same as industrial white rice flour?
No. Some people use “industrial white rice flour” as a nickname because both look like fine white powders. But they are totally different. Rice flour comes from ground rice and is used in food. Fumed silica is synthetic and used only in industrial or technical applications.
How does fumed silica improve product performance?
It acts as a thickener, anti-caking agent, and reinforcing filler. When added to liquids like sealants or coatings, it stops them from dripping. In powders, it keeps particles from sticking together. It also boosts strength in rubber and plastics without changing their color.
Is fumed silica safe for use?
Yes, when handled properly. Amorphous fumed silica is not classified as hazardous under normal conditions. It is not the same as crystalline silica, which can be harmful if inhaled. Users should still wear basic protection like masks and gloves during handling to avoid dust exposure. Always follow safety guidelines on the product label.
