Fire-Resistant Black Cotton Rock Wool Board

Fire-Resistant Black Cotton Rock Wool Board is a premium inorganic thermal insulation and fireproof material, made from high-quality basalt and other natural volcanic rocks through high-temperature melting, centrifugal fiber spinning, and high-pressure curing molding. The "black cotton" refers to its dense, deep-toned fiber structure, which delivers exceptional high-temperature resistance and mechanical strength, making it an ideal solution for industrial and building fire protection systems.

Key Performance Advantages

Class A Non-Combustible & Extreme Fire Resistance

With a melting point exceeding 1000°C, it is 90% non-combustible, effectively blocks flame spread, and meets the strictest international fire safety standards. It can maintain structural stability in high-temperature fire environments, providing reliable fire separation and protection for buildings and industrial equipment.

Outstanding High-Temperature Insulation

The dense black cotton fiber structure features extremely low thermal conductivity, delivering superior thermal insulation performance even in continuous high-temperature working conditions. It effectively reduces heat loss, saves energy consumption, and is suitable for high-temperature pipeline, kiln, and furnace insulation.

Excellent Sound Absorption & Noise Reduction

The porous, interconnected fiber network efficiently absorbs sound waves across a full frequency range, significantly reducing noise transmission. It is widely used for sound insulation in industrial workshops, building partitions, and mechanical equipment rooms.

Moisture-Proof, Corrosion-Resistant & Durable

With excellent hydrophobicity and moisture resistance, it prevents moisture penetration, mold growth, and corrosion, maintaining stable physical and thermal performance in humid environments for a long service life.

High Mechanical Strength & Easy Construction

The board has high compressive and tensile strength, is not easy to deform or damage, and can be cut, sawed, and nailed freely. It is compatible with various building structures and industrial systems, simplifying on-site construction and installation.

Main Application Scenarios

Fireproof and thermal insulation for building exterior walls, curtain walls, and roof systems

High-temperature insulation for industrial kilns, furnaces, boilers, and heat pipelines

Fire separation and fireproof sealing for building fire compartments and shaft walls

Sound absorption and noise reduction for industrial workshops, theaters, and office buildings
