Silicone-Coated Fiberglass Fabric

Properties:

1. Temperature Resistance: Can withstand higher temperatures, typically up to 500°F (260°C) or more.
2. Flexibility: Generally more flexible, especially at low temperatures.
3. Chemical Resistance: Excellent resistance to many chemicals, oils, and solvents.
4. Weather Resistance: Highly resistant to UV radiation, ozone, and weathering, making it suitable for outdoor applications.
5. Electrical Insulation: Good electrical insulating properties.

Advantages:

• Ideal for high-temperature applications like heat shields, welding blankets, and insulation covers.
• Maintains flexibility and durability across a wide temperature range.
• Long-lasting when exposed to harsh environmental conditions.

Common Uses:

• Insulation for electrical wiring and components.
• Protective covers for machinery and equipment in high-temperature environments.
• Fire protection barriers and welding curtains.
  
  

PVC-Coated Fiberglass Fabric

Properties:

1. Temperature Resistance: Lower than silicone-coated, usually up to around 140-170°F (60-77°C).
2. Flexibility: Good flexibility but can become brittle at very low temperatures.
3. Chemical Resistance: Resistant to many acids, alkalis, and salts, but less so to solvents.
4. Weather Resistance: Good, but prolonged exposure to UV can cause degradation over time.
5. Waterproofing: Excellent waterproofing properties.

Advantages:

• Cost-effective compared to silicone-coated fabrics.
• Good for moderate temperature applications and environments where waterproofing is crucial.
• Suitable for applications where chemical resistance to specific substances is needed.

Common Uses:

• Tarpaulins and covers for equipment and goods.
• Industrial curtains and partitioning.
• Ducting and ventilation systems.
• Temporary shelters and structures.
  
  

Comparative Summary

1. Temperature Resistance: Silicone-coated fabric handles higher temperatures better than PVC-coated fabric.
2. Flexibility: Silicone remains flexible in a wider range of temperatures, while PVC can become brittle in extreme cold.
3. Durability: Silicone-coated fabric generally offers better durability, especially in harsh weather and high UV conditions.
4. Chemical Resistance: Silicone-coated fabric is more resistant to a wider range of chemicals, especially oils and solvents, while PVC-coated fabric is suitable for resistance to specific acids and alkalis.
5. Cost: PVC-coated fabric is typically more economical.
   
   

Selection Criteria

• High Temperature: Choose silicone-coated fiberglass fabric.
• Chemical and Solvent Exposure: Prefer silicone-coated fabric for general chemical resistance, but consider PVC-coated fabric for specific chemicals.
• Waterproofing and Cost Efficiency: PVC-coated fiberglass fabric is a better choice.
• Outdoor Durability: Silicone-coated fabric is superior for prolonged exposure to sunlight and harsh weather.

By considering these properties and advantages, you can select the appropriate coated fiberglass fabric for your specific application requirements.
