Fire-Resistant Silicone Fiberglass Fabric for Industrial Insulation

Fire-resistant materials play a critical role in modern industrial insulation systems.
Among them, silicone fiberglass fabric has become a preferred solution for applications requiring high temperature resistance, flame protection, flexibility, and long service life.

This article explains how fire-resistant silicone fiberglass fabric works, its key properties, and why it is widely used in industrial insulation.

1. What Is Fire-Resistant Silicone Fiberglass Fabric?

Fire-resistant silicone fiberglass fabric is a composite material made by coating fiberglass cloth with fire-retardant silicone rubber.

Each layer contributes specific functions:

• Fiberglass fabric

• Non-combustible

• High tensile strength

• Excellent dimensional stability at high temperatures

• Silicone rubber coating

• Heat and flame resistance

• Waterproof and weather-resistant

• Flexible and durable

The result is a fabric that combines structural strength, thermal insulation, and fire protection.

2. How Does Silicone Fiberglass Fabric Resist Fire?

Fire resistance comes from both material selection and chemical structure.

✔ Non-Flammable Fiberglass Base

Fiberglass does not burn and can withstand temperatures above 500°C, acting as the primary fire barrier.

✔ Flame-Retardant Silicone Coating

When exposed to fire or extreme heat, silicone rubber:

• Does not drip or melt

• Forms a protective ceramic-like ash layer

• Slows heat transfer and flame spread

✔ Low Smoke & Low Toxicity Options

Special formulations reduce smoke generation and toxic gas release, improving safety in enclosed industrial environments.

3. Key Properties for Industrial Insulation

High Temperature Resistance

• Continuous working temperature: 200–250°C

• Short-term exposure: up to 300°C (depending on grade)

Excellent Thermal Insulation

Reduces heat loss and protects surrounding equipment and personnel.

Flexibility & Mechanical Strength

Unlike rigid insulation materials, silicone fiberglass fabric:

• Remains flexible after heat exposure

• Resists tearing and cracking

• Adapts to complex shapes and moving equipment

Weather & Aging Resistance

Resistant to:

• UV radiation

• Ozone

• Moisture

• Industrial aging

Ensuring long-term reliability.

4. Common Industrial Applications

Thermal Insulation Jackets

• Valves

• Pipes

• Flanges

• Pumps

Used in oil & gas, chemical plants, and power stations.

Fire Protection Systems

• Fire curtains

• Fire blankets

• Fire barriers

Expansion Joints & Flexible Connectors

• Compensate for thermal expansion

• Absorb vibration

Protective Covers

• Welding protection

• Heat shields

• Equipment protection covers

5. Fire-Resistant Silicone Fiberglass Fabric vs Other Materials

Silicone fiberglass fabric offers the best balance between fire resistance, flexibility, and durability.

6. Customization Options for Industrial Use
