Flame-Retardant Silicone Sheet: An Ideal Material for Industrial Safety and High-Temperature Environments

Flame-Retardant Silicone Sheet: An Ideal Material for Industrial Safety and High-Temperature Environments

As industrial automation and smart equipment continue to advance, the working environments of machinery are becoming increasingly complex. In high-temperature, high-voltage, and fire-prone conditions, material safety performance is critical. Flame-retardant silicone sheets, with their outstanding fire resistance and thermal stability, have become indispensable functional materials in industries such as electrical power, electronics, rail transportation, and aerospace.

Key Features of Flame-Retardant Silicone Sheets

Flame-retardant silicone sheets are made from high-purity silicone rubber combined with eco-friendly flame retardants, formed through high-temperature calendaring or compression molding. They offer the following core features:

1. Excellent Flame Retardancy

Certified to UL94 V-0 rating, the material is self-extinguishing once the fire source is removed. It does not drip or propagate flames, significantly reducing fire hazards to personnel and equipment.

2. Outstanding Thermal Resistance

The sheet maintains stable physical properties across a wide temperature range from -60°C to +200°C. It remains flexible and durable without softening or cracking under extreme conditions.

3. Superior Electrical Insulation

Silicone rubber naturally has high electrical resistance. The flame-retardant formula does not compromise insulation properties, making it ideal for use in electrical devices and power systems.

4. Flexible and Easy to Install

With excellent softness and elasticity, the sheet can be easily cut, punched, and applied to complex surfaces, enabling quick and efficient installation.

Wide Applications Across Industries

Thanks to its comprehensive performance, flame-retardant silicone sheets are widely used in:

Electrical Industry: As insulation pads and fire barriers in control cabinets, transformers, and distribution boxes.

Rail Transit: For flame-blocking and sealing of electrical components inside subway and train cabins.

New Energy Equipment: In charging stations, energy storage systems, and other high-demand environments.

Electronics Manufacturing: As high-temperature worktable pads or thermal insulation layers to protect equipment and operators.

Aerospace & Defense: For sealing, shock absorption, and flame protection in precision systems.
