Core Product Characteristics

Superior Fire Separation & High-Temperature Resistance

As the core performance of the product, it is an inherent non-combustible material that can withstand high temperatures up to 600℃ and has a high hot load shrinkage temperature. In fire conditions, it does not burn, melt or release toxic smoke and combustible gases, effectively blocking the vertical and horizontal spread of fire between building floors and facades, and winning precious evacuation time for personnel. Its organic content is strictly controlled at an ultra-low level through professional detection (combustion method/chemical analysis), with no combustion-supporting components in the material, and the fireproof performance fully meets the national and industrial special standards for building fire barrier belts.

Enhanced Structural Strength & Installation Stability

Targeted at the strip installation form of fire barrier belts, the product has optimized fiber distribution and strict slag ball content control (the proportion of particles with diameter ＞0.25mm is in line with the high standard of building insulation materials). It has outstanding compressive and tensile strength, can withstand long-term external pressure, wind load and structural vibration without deformation, cracking or falling off, and can form a continuous and firm fire isolation layer after installation. The product’s density is designed in the range of 100-160kg/m³ (matching the fire barrier belt’s professional specification requirements), ensuring close combination with the building’s external wall and curtain wall structure, and avoiding fire leakage caused by material deformation.

Integrated Fireproof & Insulation Performance

While realizing the core fire separation function, it retains an extremely low thermal conductivity, which can effectively block heat transfer in normal use conditions, reduce building energy consumption and maintain indoor temperature stability. It realizes the dual effect of fire barrier and energy-saving insulation, avoiding the need for additional insulation materials in fire barrier belt engineering, simplifying the construction process and saving project costs. Its volume water absorption is extremely low and hydrophobic rate is high, which can keep the insulation and fireproof performance stable even in outdoor humid environments, without performance degradation caused by water absorption.

Excellent Environmental Adaptability & Durability

The product has good chemical stability, with strong resistance to acid and alkali corrosion, ultraviolet radiation and outdoor temperature changes, and can maintain stable physical and chemical properties for a long time when used in the external fire barrier belt of buildings. It is not easy to get damp and moldy, and effectively resists the erosion of rain, snow and fog in the natural environment, avoiding structural damage and performance attenuation of the fire barrier belt, and the service life is highly consistent with the building’s main structure, reducing later maintenance costs.

Eco-Friendly & Healthy & Green Construction Compliance

The product is a formaldehyde-free environmental protection material, without adding any harmful additives in the production process, and no toxic and harmful gases are released during construction and long-term use, complying with the national green building and indoor environmental quality standards. Its production process has low emissions, and the waste materials can be recycled and reused, in line with the low-carbon and environmental protection development concept of the construction industry, and will not cause environmental pollution and health hazards to the construction site and building interior.

Good Matching & Multi-Functional Auxiliary Advantages

It retains the porous structure of rock wool materials, with good sound absorption and noise reduction performance, which can absorb part of the outdoor environmental noise while realizing fire separation, and optimize the building’s acoustic environment. It also has appropriate air permeability, which can promote air circulation of the building’s external wall system, reduce the risk of condensation water formation in the wall, protect the building’s external wall structure from moisture damage, and improve the overall durability of the external wall system. The product’s performance and specifications are highly matched with various building external wall insulation materials (such as external wall external insulation rock wool boards), realizing seamless connection of the fire barrier belt and the external wall system.
