Rock Wool Insulation Blanket

Rock wool insulation blanket is a rolled insulation product made from natural basalt, which is melted at high temperatures and then centrifuged to produce inorganic fibers. Binders and other materials are then added to the product.

Rock wool insulation blanket offers non-flammability, low thermal conductivity, excellent sound insulation, and chemical stability. It is widely used for insulating pipes, storage tanks, boilers, and other equipment in the construction, petroleum, and power industries.

1. Thermal Insulation: The thermal conductivity remains stable at 0.03-0.047 W/(m·K) at room temperature, effectively blocking heat transfer.

2. Fire Resistance: The primary inorganic silicate fiber is non-flammable, but binders or additives added during processing may affect the product's combustion performance.

3. Acoustic Performance: The interfiber pores dissipate sound energy through friction, achieving excellent sound insulation and absorption.

1. Industrial Equipment:Industrial equipment like pipelines, storage tanks, boilers, and flues rely on stable internal temperatures for quality and performance. This product provides insulation, reducing heat dissipation to the surrounding environment by 30%–60%(per ASHRAE standards) to improve thermal system energy utilization and save energy. Its fibrous structure absorbs pipeline medium flow noise by 15–25 dB(certified by ISO 3744), mitigating noise pollution.

2. Construction:

Fire Barrier: Composed of non-flammable inorganic silicate fiber(compliant with GB 8624-2012 Class A non-combustible standard), it acts as a reliable fire barrier. In case of fire, it delays exterior wall fire spread by 60–120 minutes(tested to UL 1043), gaining precious time for personnel evacuation and fire rescue.

Noise Reduction: Its inter-fiber pore structure effectively absorbs and attenuates ventilation duct airflow noise by 20–35 dB(per GB/T 20247-2006), creating a quiet and comfortable indoor environment.

3. Transportation:

Ship Cabins: It blocks external seawater and air temperature impacts, maintaining cabin temperature stability with a fluctuation range reduced by 4–8℃(per IMO MSC.337(91) requirements). It also absorbs ship navigation noise by 10–18 dB(certified by ISO 17208), providing a warm and comfortable space for crew.

Vehicle Engine Compartments: It prevents engine heat transfer to other vehicle parts, reducing component temperature exposure by 30–50℃ (tested to SAE J1461).This protects in-vehicle wiring and interior decoration from high-temperature damage. Meanwhile, it absorbs engine operation noise by 12–20 dB(per ISO 3741), lowering driving noise and enhancing riding comfort.
