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.

5 FAQs of High Quality Hot Hydrophilic Fumed Silica Silicon Dioxide Sio2 CAB-O-SIL EH-5 For Silicone Rubber

High Quality Hot Hydrophilic Fumed Silica Silicon Dioxide Sio2 CAB-O-SIL EH-5 is a top reinforcing filler for silicone rubber. It improves key properties. Many people ask common questions about it.

What exactly is CAB-O-SIL EH-5? It’s very fine silica powder. It’s made by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates tiny particles. These particles link into chains. The result is a high-purity, high-surface-area powder. It’s hydrophilic. This means it attracts water.

Why use CAB-O-SIL EH-5 in silicone rubber? Silicone rubber needs reinforcement. Pure silicone rubber is weak. Adding EH-5 makes it much stronger. It also improves tear resistance. The rubber keeps its flexibility. It handles heat better.

How does EH-5 reinforce the rubber? The tiny silica particles mix into the silicone polymer. They form a strong network inside the rubber. This network carries loads. It stops the rubber from stretching too much. It prevents tearing easily. The rubber gets tougher overall.

Does EH-5 make the silicone rubber thicker? Yes, it does. Adding EH-5 increases the viscosity. The uncured rubber paste gets stiffer. This is normal for reinforcing fillers. Mixing takes more effort. The final cured rubber is much stronger though. The trade-off is worth it.

How much EH-5 should I use? The right amount depends on the rubber type. It depends on the properties you need. Typical loading ranges are 5% to 35% by weight. Higher loading gives stronger reinforcement. It also makes the uncured mix thicker. Start with supplier recommendations. Test different levels for your specific product.
