Silicone Coated Fiberglass Fabric: High-Temperature Protection for Industrial & Commercial Applications

2025/4/3

Engineered for extreme environments, Silicone Coated Fiberglass Fabric combines the strength of fiberglass with the versatility of silicone rubber. This article explores its unique properties, applications, and why it’s the preferred choice for high-temperature insulation, fire protection, and industrial sealing.

When industrial environments demand materials that can withstand extreme heat, harsh chemicals, and abrasive conditions, Silicone Coated Fiberglass Fabric rises to the challenge. Engineered with advanced composite technology, this high-performance material delivers unmatched protection while maintaining flexibility and durability.


What is Silicone Coated Fiberglass Fabric?

This composite material consists of a woven fiberglass base coated with high-temperature silicone rubber. The fiberglass provides dimensional stability, while the silicone layer offers:
Thermal resistance up to 300°C (short-term peaks to 500°C)
Water and chemical repellency
Flame retardancy (UL 94 V-0 rating)
Flexibility for complex shapes

Applications Across Industries

1. Industrial Machinery

  • Heat Shielding: Protects wires, cables, and components in furnaces, boilers, and ovens.

  • Duct Sealing: Used in flexible connectors for HVAC systems (resists condensation).

  • Pipe Insulation: Prevents heat loss in steam pipelines (reduces energy costs by 15–20%).


2. Automotive & Aerospace

  • Exhaust Systems: Insulates headers and turbochargers to improve performance.

  • Fire Barriers: Installed in engine compartments to meet safety standards.

  • Composite Tooling: Used as a release agent in aerospace component manufacturing.


3. Construction & Architecture

  • Fire Curtains: Rated for 2–4 hours of fire resistance (ASTM E119).

  • Roofing Membranes: Reflects solar heat to reduce cooling costs.

  • Seismic Isolation: Used in building joints to absorb vibrations.


4. Electrical & Electronics

  • Insulating Sleeves: Protects wires in transformers and power generation equipment.

  • EMI/RFI Shielding: Coated variants block electromagnetic interference.

  • Battery Thermal Management: Used in EV battery packs to prevent thermal runaway.
