Pure asbestos sheet—also known as asbestos millboard—is a heat-resistant insulating material manufactured from high-quality asbestos fibers. It is designed for environments that require reliable thermal protection, flame resistance, and structural stability. Thanks to its excellent insulating performance, the sheet is commonly used in furnace linings, heat shields, fire barriers, and various industrial applications where high-temperature endurance is essential.

Features

High-Temperature Performance
Engineered to withstand continuous exposure to 400°C–1400°C, the sheet provides dependable thermal insulation for demanding heat-intensive operations.

Strong Mechanical Properties
With tensile strength ranging from 12–14 kg/cm², the board maintains integrity under load while remaining easy to cut and shape for installation.

Low Ignition Loss
A loss-on-ignition value of less than 18% ensures excellent fire resistance and long-term stability in high-heat environments.

Consistent Density & Structure
The uniform density of 1.3 g/cm³ gives the sheet good rigidity and durability, allowing it to serve effectively as a barrier, lining, or protective layer.

Electrical Insulation Capability
Beyond heat protection, pure asbestos sheet also offers basic electrical insulation properties, making it suitable for specific industrial electrical shielding needs.
