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.

Applications of Industrial HTV Silicone Rubber Solid silica Gel General Purpose Silicone Rubber For Molding (Precipitated/Fumed)

Industrial HTV silicone rubber solid silica gel serves multiple purposes across industries. This material works for molding processes requiring heat resistance, durability, flexibility. It handles high temperatures, harsh chemicals, mechanical stress. The product comes in two types: precipitated silica gel and fumed silica gel. Both types offer strong performance but differ in production methods, cost, specific uses.

Precipitated silica gel suits general-purpose applications. It provides good reinforcement, cost efficiency. Manufacturers use it for molds in plastic parts, rubber components, low to medium precision tools. The material resists wear, maintains shape under pressure. Automotive industries apply it for gaskets, seals, vibration dampeners. Electronics manufacturers use it for insulating parts, protective casings.

Fumed silica gel targets high-performance needs. It offers superior strength, thermal stability. This type fits complex molds, precision instruments, high-temperature tooling. Aerospace and defense sectors rely on it for engine components, heat shields, custom seals. Medical device makers choose it for sterile, non-reactive molds. The material meets strict hygiene standards, handles repeated sterilization.

Both silica gel types adapt to custom formulations. Users adjust hardness, viscosity, curing speed. This flexibility supports diverse production needs. Construction industries apply silicone rubber for weatherproofing seals, expansion joints. The material withstands UV exposure, temperature swings, moisture.

Industrial HTV silicone rubber remains stable from -50°C to 250°C. It resists ozone, oxidation, aging. These traits ensure long service life in demanding environments. The rubber bonds well with metals, plastics, fabrics. This aids multi-material molding processes.

Automation-friendly properties make the material efficient for mass production. It cures quickly under heat, reduces cycle times. Users achieve consistent results, minimal waste. Food processing equipment manufacturers use FDA-compliant grades. The rubber avoids contaminating products, endures frequent cleaning.

Electrical industries value its insulation properties. The material prevents current leakage, resists arc tracking. Power distribution systems, cable accessories benefit from its reliability. Custom colors, textures allow branding or functional coding.

The product’s versatility stems from balanced physical traits. It fills gaps between rigid materials, absorbs vibrations. Heavy machinery, consumer goods, renewable energy systems all utilize its adaptive nature.

5 FAQs of Industrial HTV Silicone Rubber Solid silica Gel General Purpose Silicone Rubber For Molding (Precipitated/Fumed)

Industrial HTV silicone rubber solid silica gel is used for molding. It works in general-purpose applications. People often have questions about its features. Here are common ones answered.

What temperature range does this silicone rubber handle? It resists temperatures from -50°C to 250°C. This makes it suitable for high-heat environments like automotive parts or industrial machinery. It keeps its shape under extreme conditions.

How long can the material stay usable before curing? Unopened packages last 12 months if stored properly. Keep it in a cool, dry place away from sunlight. Once opened, use it within six months. Check for changes in texture or color before use.

Is this silicone rubber safe for food-related molds? No. This product isn’t food-grade. It lacks certifications for direct contact with food. Use it for industrial molds only. For food applications, choose a silicone labeled as food-safe.

What’s the difference between precipitated and fumed silica versions? Precipitated silica has larger particles. It offers good reinforcement at lower cost. Fumed silica has finer particles. It provides higher strength and better clarity. Pick precipitated for basic molds. Choose fumed for precision or high-performance needs.

Can it cure without pressure? Yes. It cures at room temperature with a catalyst. Pressure isn’t required. Apply heat if faster curing is needed. Heat reduces curing time but follow guidelines to avoid defects.

This covers key points users ask about. The material’s versatility makes it popular for industrial molding. Always check technical specs for specific project requirements.
