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.

Useful Benefits in PVC Applications

Fusil 200 serves as a reliable anti-settling and thickening representative in PVC formulations. It protects against pigment and filler splitting up during storage and processing. The silica particles develop a three-dimensional network that maintains the mixture without compromising quality or adaptability.

This grade improves thaw toughness during extrusion and calendering, minimizing droop and distortion in final products. It likewise boosts surface area finish and scrape resistance in inflexible and versatile PVC products such as wires, floor covering, films, and profiles.

Due to the fact that it is hydrophilic, Fusil 200 incorporates smoothly into aqueous systems and typical PVC compounding processes. No surface treatment is needed, which simplifies manufacturing and keeps price efficiency.

Handling and Storage

Store in a dry, cool location in sealed containers to prevent dampness absorption. Use standard commercial health techniques when taking care of fine powders– use safety gloves, eye protection, and a dirt mask. Avoid solid acids and bases to preserve item integrity.

Applications of Fusil 200 Hydrophilic Fumed Silica in PVC Resin

Improved Performance in PVC Formulations

Fusil 200 hydrophilic fumed silica (SiO TWO, CAS 231-545-4) is a high-purity industrial-grade white carbon black powder. It works well as a functional additive in polyvinyl chloride (PVC) resin systems. The great fragment dimension and big surface aid improve crucial physical properties of PVC compounds.

Enlarging and Anti-Settling
This silica serves as a reliable thickening agent. It protects against pigments and fillers from working out throughout storage or handling. That keeps the PVC blend attire and steady over time.

Rheology Control
Fusil 200 gives far better control over flow habits. This is very important for extrusion, calendering, and injection molding. The product relocates efficiently via equipment without sagging or trickling.

Mechanical Toughness
Adding small amounts of this fumed silica boosts tensile strength and tear resistance. PVC products come to be much more resilient without losing flexibility.

Surface area Finish
The powder helps create smoother surface areas on completed PVC products. It decreases surface area issues and improves gloss consistency. This matters for applications like floor covering, wires, and artificial natural leather.

Handling Help
Fusil 200 additionally sustains less complicated processing. It reduces friction in between polymer chains during blending and shaping. This lowers energy usage and wear on machinery.

Producers utilize this hydrophilic silica in inflexible and adaptable PVC alike. Regular loadings vary from 0.1% to 2.0% by weight, relying on the preferred result. The item satisfies conventional industrial purity demands and blends easily right into completely dry blends or liquid dispersions.

Because it is hydrophilic, Fusil 200 works best in systems with low dampness level of sensitivity. It should be saved in a completely dry area to preserve performance. Appropriate dispersion– using high-shear mixing– is vital to getting complete benefits in the last PVC product.

5 FAQs of Fusil 200 Hydrophilic Fumed Silica for for PVC Resin White Carbon Black Sio2 Silicon Dioxide Industrial Grade Powder 231-545-4

Frequently Asked Questions About Fusil 200 Hydrophilic Fumed Silica

What is Fusil 200 Hydrophilic Fumed Silica?

Fusil 200 is a high-purity white powder made of silicon dioxide (SiO₂). It is also known as hydrophilic fumed silica or white carbon black. This industrial-grade material has the CAS number 231-545-4. It mixes well with water and is commonly used to improve performance in PVC resin and other polymer systems.

How does it work in PVC resin?

Fusil 200 acts as a thickening and anti-settling agent in PVC formulations. It helps keep pigments and additives evenly spread. The powder also boosts mechanical strength and improves surface finish. Because it is hydrophilic, it bonds easily with polar substances found in many PVC compounds.

Is Fusil 200 safe to handle?

Yes, but standard safety practices must be followed. Wear gloves, eye protection, and a dust mask when handling the powder. Avoid breathing in fine particles. Store in a dry place away from moisture to maintain its quality and flowability.

What makes Fusil 200 different from other silica products?

Fusil 200 is made through a flame hydrolysis process. This gives it a very fine particle size and high surface area. These features create strong thickening power even at low dosages. Its hydrophilic nature means it works better in water-based or polar systems than hydrophobic grades.

How should I add Fusil 200 to my PVC mix?

Add the powder slowly during the mixing stage. Use high-shear mixing to break up clumps and ensure even dispersion. Typical usage levels range from 0.5% to 3% by weight, depending on your formula and desired results. Always test small batches first to find the best amount for your application.
