A 3mm asbestos millboard sheet is a rigid, high-temperature, and fire-resistant insulation material manufactured from compressed asbestos fibers combined with incombustible fillers and binders. It is primarily used in various industrial applications for thermal insulation and fire protection. Key Characteristics & Properties
Material: Composed mainly of high-grade asbestos fibers.
Thickness: 3 mm (also available in various other thicknesses from 1.5mm to 12mm).
Color: Typically grey or off-white.
Size: Commonly available in square sheets, often 1 meter x 1 meter (approx. 40 x 40 inches).
Temperature Resistance: Designed to withstand high temperatures, typically up to 450°C to 500°C, and higher when adequately supported (up to 1000°C or 1400°C depending on the grade).
Properties:
Excellent thermal and electrical insulation.
Strong, flexible, and durable.
Resistant to wear, heat, flame, acids, and vermin.
