Application of insulation cotton

Insulation cotton (space cotton, glass wool, needle-punched space cotton, rock wool, ceramic fiber, aerogel, rubber and plastic, etc.) is a core energy-saving and safety material in the fields of building energy efficiency, industrial heat, HVAC and refrigeration, transportation cold chain, and new energy, relying on its core advantages such as thermal insulation, fire resistance, sound absorption, lightweight, and corrosion resistance.
1. Construction industry (the largest application market)
External wall/internal wall insulation: Rock wool and glass wool boards are used for external insulation, internal insulation, and sandwich walls of external walls, reducing air conditioning/heating energy consumption by 20%-30%.
Roof/attic insulation: Roll materials and felt-type roofing are used for insulation in summer and heat retention in winter.
Insulation for air conditioning ducts/water pipes: Glass wool and rubber-plastic casing are used to wrap air ducts and chilled water pipes, reducing cold loss and noise reduction.
Fire protection and insulation for steel structures: Rock wool wrapped around steel beams and columns, Class A non-combustible, high temperature resistant up to 700℃, and heat-insulating.
Fire barrier: Rock wool board is used as a fire barrier on the exterior walls of high-rise buildings to prevent the spread of fire.
Acoustic noise reduction: Glass wool/rock wool sound absorption for cinemas, stadiums, and computer rooms.
2. Industrial Thermal Power and Petrochemical (Core of High-Temperature Energy Saving)
Steam/high-temperature pipeline insulation: Rock wool, aluminum silicate, and aerogel wrapped around **300–600℃** steam pipes reduce heat loss by over 30%.
Industrial kiln/boiler lining: ceramic fiber (1260℃+), rock wool as lining, and backing insulation.
Petrochemical reactors/pyrolysis furnaces: High-temperature equipment insulation for energy saving, stable process temperature, and personnel protection.
Thermal power plant: Insulation of boilers, steam turbines, and flues to enhance power generation efficiency and reduce coal consumption.
Metallurgy / Steel: Insulation for blast furnaces, hot blast stoves, and heat treatment furnaces, and improvement of workshop environment.
3. HVAC & Refrigeration and Cold Chain (Low Temperature Cold Preservation)
Central air conditioning system: Rubber and plastic, glass wool are used for chilled water/cooling water pipelines, fan coils, and air conditioning units.
Cold storage/cold chain logistics: Rubber, plastic, and aerogel are used for cold storage walls, cold chain compartments, and refrigerated trucks, providing cold insulation and anti-condensation from -40℃ to 0℃.
LNG/Cryogenic Engineering: **-162℃** LNG storage tanks and pipelines require cold insulation to prevent cold bridges and frost formation.
4. Transportation and Vehicles
Automotive: engine compartment heat shield, exhaust pipe wrapping (ceramic fiber), interior sound absorption, thermal management of new energy battery pack.
Rail transportation: insulation and noise reduction for the body, roof, air conditioning system, and equipment cabin of high-speed rail/bullet trains.
Ship: The ship's cabins, air conditioning ducts, and engine rooms are insulated, moisture-resistant, fire-resistant, and comply with maritime standards.
5. New energy and electric power
Photovoltaic/Wind Power: Inverters, Transformers, Internal Insulation and Fire Protection for Tower Tubes.
Energy storage / lithium battery: battery pack, thermal management of containerized energy storage systems, fire prevention and insulation, temperature difference control.
Power equipment: transformers, switchgear cabinets, fireproof sealing and insulation for cable trenches, as well as noise reduction through thermal insulation.
6. Home Appliances and Electronics
Home appliances: refrigerator, freezer, water heater, wall-mounted boiler, oven liner/outer shell insulation, energy saving.
Electronic equipment: cabinets, servers, precision instruments - temperature control, insulation, fire prevention, noise reduction.
7. Other industries
Fire prevention: fireproof door core, fireproof cable wrapping, fireproof sealing materials.
Shipbuilding / Marine Engineering: Salt spray resistance, water repellency, fireproofing and insulation.
Aerospace: High-end aerogel and ceramic fiber are used for thermal insulation in aircraft and engines.
