Loose Rock Wool Fill for Cavity Insulation - China Suppliers and Factory for Thermal, Fireproof, and Acoustic Applications
Fire Resistance
ABM® Rock Wool is made from natural rock and is a Class A non-combustible material. With a melting point above 1000°C, it effectively slows down fire spread. In case of fire, it does not release toxic gases or molten droplets. Its excellent high-temperature performance and low thermal conductivity under extreme heat provide critical time to save lives and reduce property damage.
Thermal Insulation
ABM® Rock Wool has been tested according to international standards such as ASTM C518/C177. It exhibits consistently low thermal conductivity across a wide temperature range, with superior thermal stability and environmental adaptability. Ideal for demanding industrial insulation and fireproof applications.
Water Repellency
ABM® ensures that industrial insulation layers remain dry in humid environments, maintaining stable thermal conductivity, preventing energy loss and metal corrosion, and significantly enhancing system durability and energy efficiency.
Safety & Environmental Friendliness
ABM® Rock Wool is asbestos-free. The International Agency for Research on Cancer (IARC) classifies rock wool products as Group C – not carcinogenic. Water extracts are neutral to mildly alkaline, causing no harm or corrosion to materials in contact. Free of CFCs, HCFCs, and HFCs.
Sound Absorption
ABM® Rock Wool’s fibrous structure forms a highly porous interconnected network, ensuring excellent acoustic absorption and noise reduction. It significantly minimizes sound reflection and transmission, creating a disturbance-free environment for work and living.
Weather Resistance
ABM® Rock Wool is resistant to freeze-thaw cycles and UV exposure. It does not expand or contract with seasonal temperature variations and can perform reliably under extreme climates without being affected by other materials.
Energy Saving
The energy saved during ABM® Rock Wool’s use exceeds the energy consumed in its production, transportation, and recycling by over 100 times.
Ease of Installation
ABM® Loose Fill Wool can be applied by spraying or manual filling, greatly improving installation efficiency in complex conditions and effectively reducing labor costs.
Low Chlorine
ABM® Low-Chlorine Rock Wool is chemically stable, resistant to degradation from chloride migration, and ensures that insulation systems maintain a consistently low thermal conductivity throughout their service life. Its durability matches that of the equipment, avoiding frequent replacement and maintenance costs.
Outstanding Filling Adaptability
With excellent flowability, granular form easily fills irregular cavities and complex structures, achieving seamless insulation without dead zones.
