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.

Specification of Whole Raw material fumed silica Silicon Dioxide for insulated panel

Our fumed silica silicon dioxide is the crucial basic material for top-performing insulated panels. This product is a fluffy white powder. It originates from shedding silicon tetrachloride in a hydrogen-oxygen flame. This procedure produces extremely great particles. These particles connect right into complicated three-dimensional chains. The chains form a light, porous framework.

This framework provides fumed silica its distinct properties. It has an exceptionally high surface. This surface traps air effectively. Caught air blocks heat transfer. This makes the silica an impressive insulator. It likewise enhances the foam matrix within the panel. This support enhances the panel’s stamina. It likewise assists the panel keep its form with time.

Our whole basic material fumed silica meets stringent requirements. It flaunts exceptional pureness, commonly surpassing 99.8% silicon dioxide material. Reduced degrees of impurities like chloride and aluminum are assured. These reduced levels prevent deterioration. They likewise guarantee consistent foam reaction chemistry. The details surface is snugly managed. This location generally varies between 150 and 400 square meters per gram. Exact control maximizes enlarging and support.

The powder has a very low mass density. This low thickness makes it easy to mix into material systems. It spreads well. Excellent dispersion is important for consistent foam residential properties. The product is additionally highly hydrophobic. This implies it fends off water. Water resistance is crucial for long-lasting insulation efficiency. Dampness can spoil insulation worth.

Fumed silica supplies integral fire resistance. It does not burn. It creates a safety char layer when subjected to fire. This layer guards the hidden material. It reduces flame spread. This characteristic boosts the safety and security of insulated panels. We make certain constant bit size circulation. Constant dimension avoids clumping. It guarantees foreseeable processing actions during panel manufacture. Deal with the powder thoroughly. Stay clear of developing dirt clouds. Shop it in a trendy, dry location. Maintain it sealed in its initial product packaging.

Applications of Whole Raw material fumed silica Silicon Dioxide for insulated panel

Fumed silica is a special form of silicon dioxide. It is made by burning silicon tetrachloride in a fire. This produces really great fragments. These particles are extremely tiny and light. They resemble a white powder. This powder is very helpful in insulated panels.

Shielded panels require to quit warmth relocating via them. Fumed silica assists a great deal with this. It imitates small blocks. These blocks trap air inside the panel core. Air is a good insulator. Catching air quits heat flowing quickly. This makes the panel much better at keeping warmth in or out.

Fumed silica additionally makes panels lighter. The powder itself doesn’t consider much. Including it to the core material does not add extra weight. Light panels are simpler to take care of. They are likewise less costly to carry. Home builders prefer lighter materials.

Fire safety and security is very essential in structures. Fumed silica is normally fire resistant. It doesn’t melt quickly. Including it to the panel core aids the whole panel stand up to fire better. This improves structure safety and security.

The powder blends well with other materials. Manufacturers use it in polyurethane or polyisocyanurate foam cores. It aids the foam set correctly. It makes the foam framework stronger. This indicates the panel remains effective for longer. The panels withstand damages much better.

5 FAQs of Whole Raw material fumed silica Silicon Dioxide for insulated panel

Here are 5 common questions about Whole Raw Material Fumed Silica (Silicon Dioxide) for insulated panels:

What is fumed silica exactly? Fumed silica is a very fine white powder. We make it by burning silicon tetrachloride in a hydrogen-oxygen flame. This creates tiny particles of pure silicon dioxide. These particles are extremely small. They form tangled chains. This structure gives fumed silica unique properties.

Why use fumed silica in insulated panels? Fumed silica is key for high-performance insulation. Its tiny particles trap air incredibly well. Trapped air stops heat moving through the panel. This creates excellent thermal resistance. Fumed silica also makes the core material very light. Lightweight panels are easier to handle and install.

What properties make it special? Fumed silica has a huge surface area. This helps it absorb other materials effectively. It thickens liquid resins. It prevents settling in mixtures. Fumed silica reinforces the panel core. It makes the core stronger. It also helps the core resist crushing. Panels keep their shape better over time. Many types are hydrophobic. This means they repel water. Water resistance protects the insulation value.

Is this material safe? Pure fumed silica is generally safe. It is chemically inert. It doesn’t react easily. It is non-toxic. You still need care when handling the powder. Breathing in any fine dust can irritate lungs. Always wear proper dust masks. Follow safety guidelines. Use good ventilation.

How should we handle and store it? Keep fumed silica completely dry. Moisture ruins its performance. Store bags sealed tightly. Keep them in a dry place. Handle bags carefully. Avoid rough treatment. This prevents the powder from packing too hard. Packed powder is difficult to mix later. Use it before its recommended shelf life expires.
