Rock Wool Blanket

Rock Wool Blanket is a flexible, roll-type thermal insulation and fireproof product independently produced by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd., a classic member of the rock wool product series. Taking high-quality basalt and other natural rock minerals as the core raw materials, it is made through advanced processes of high-temperature melting, high-speed centrifugal spinning to form continuous fibers, fiber laying, curing and roll forming. Different from the rigid rock wool board, it features flexibility, light weight and easy construction, and retains all the excellent performance of rock wool materials such as A-class non-combustibility, thermal insulation, sound absorption and corrosion resistance. It can be arbitrarily cut, folded and wrapped, and is specially suitable for the thermal insulation, fireproof and sound absorption of irregular-shaped objects such as industrial pipelines, large-scale equipment and curved building structures. It is a widely used functional insulation material in civil construction, industrial insulation, marine engineering and municipal engineering.

Core Product Characteristics

Superior Fire Resistance & High-Temperature Stability

As an A-class non-combustible material, it is made of inorganic rock fibers with a melting point of more than 1000℃ and can withstand high temperatures up to 600℃ with an excellent hot load shrinkage temperature. In case of fire, it will not burn, melt or release toxic smoke and combustible gases, and can maintain structural stability without shrinkage and deformation, effectively blocking the spread of fire and heat transfer. Its organic content is strictly controlled at an ultra-low level, and the slag ball content (particles with diameter ＞0.25mm) is ≤10%, which fully meets national and industrial fire safety standards, and is an ideal fireproof material for high-temperature industrial environments and building fire protection systems.

Efficient Thermal Insulation & Energy Saving

It has an extremely low thermal conductivity of only 0.032-0.040W/(m·K) at 70℃, which is far lower than that of traditional thermal insulation materials. The dense and fluffy fiber structure forms a large number of closed air chambers, which can effectively block heat conduction and convection, and achieve excellent thermal insulation effects even in thin thickness. It can significantly reduce heat loss of industrial pipelines and building envelope structures, lower energy consumption of heating and cooling systems, and meet the national "double carbon" strategic goals of energy conservation and emission reduction.

Excellent Sound Absorption & Vibration Reduction

The three-dimensional porous fiber structure can effectively absorb sound wave energy, convert sound energy into heat energy and dissipate it, with a noise reduction coefficient (NRC) of up to 0.85 and a weighted sound insulation (Rw) of 30dB for the 50mm thick product. It can significantly reduce environmental noise and mechanical vibration noise, and also has good elastic vibration damping performance, which can reduce the resonance of pipelines and equipment during operation, protect the structure from vibration damage, and is suitable for noise reduction and shock absorption in high-noise scenarios such as industrial workshops, airports and subway stations.

Flexible & Easy Construction & Strong Adaptability

As a roll-type flexible material, it has good ductility, can be arbitrarily cut, folded, wrapped and laid, and is perfectly adapted to the thermal insulation and fireproof construction of irregular-shaped objects such as large-diameter pipelines, curved tanks, boiler equipment and special-shaped building structures. It is light in weight, easy to transport and construct, and can be installed by binding, pasting and wrapping without complex construction equipment, greatly improving construction efficiency, especially suitable for the rapid construction of large-scale industrial insulation projects.

Superior Water & Moisture Resistance & Durability

It has a high hydrophobic rate of ≥90% and extremely low volume water absorption, with no capillary water seepage phenomenon. The fiber surface has good water repellency, which can effectively resist the erosion of water vapor, rain and snow, and maintain stable thermal insulation and mechanical properties even in humid environments such as coastal areas and underground spaces. It has excellent chemical stability, no corrosion to metal pipelines and building components, no moth-eaten and mildew, and can be used for a long time in harsh environments such as acid and alkali mist, with low later maintenance costs.

Eco-Friendly & Healthy & Recyclable

It is made of natural inorganic rock minerals, without adding formaldehyde, asbestos and other harmful additives, and no toxic and harmful gases are released during production, construction and long-term use, complying with national green building and indoor environmental quality standards. The product is non-toxic and harmless to the human body, and the chloride ion content is ≤10ppm, which is safe to use with stainless steel products. The production process has low energy consumption and low emissions, and the waste materials can be recycled and reused without polluting the environment, in line with the concept of low-carbon environmental protection.

Diverse Types & Scenario Customization

According to different application scenarios and functional requirements, it can be processed into multiple types including plain felt, wire mesh stitched felt and glass fiber cloth stitched felt. The wire mesh stitched felt is reinforced with metal wire mesh, with higher tensile strength and structural stability, suitable for high-temperature and high-vibration industrial environments; the glass fiber cloth stitched felt has good dustproof performance, suitable for building wall insulation and equipment dustproof protection, meeting the diversified needs of different scenarios.
