With the advantages of flexible construction, ultra-efficient thermal insulation, high temperature resistance, fire resistance, hydrophobicity and weather resistance, aerogel glass fiber thermal insulation blanket has been widely applied in six core fields: industrial heating, petrochemical industry, electric power energy, rail transit, marine engineering and building fire protection. It is the preferred flexible insulation material for high-temperature equipment, heat pipelines and closed cabins. Compared with traditional rock wool, silicate cotton and ordinary glass fiber products, it has remarkable advantages in energy saving, service life, construction experience and safety protection. Driven by the carbon peaking and carbon neutrality goals, it has become the mainstream material for industrial energy-saving renovation and new construction projects.
Petrochemical industry and heating pipe networks are its largest application scenarios. In petrochemical plants, high-temperature reactors, distillation equipment and transmission pipelines work continuously at 300~600℃. Traditional insulation materials have poor thermal performance and fast aging, resulting in high heat loss and maintenance costs every year. Wrapped with aerogel glass fiber insulation blanket, the thickness of insulation layer is greatly reduced, the surface temperature of pipelines is kept within a safe range, and heat loss is cut by more than 40%. The material resists medium corrosion and thermal shock, with an outdoor service life of more than 15 years, much longer than the 3 to 5 years of traditional materials. In urban central heating networks and industrial steam pipeline renovation projects, the light and flexible blanket is suitable for special-shaped components such as elbows, valves and flanges, doubling the construction efficiency and solving the problems of insulation failure and heat leakage of old pipe networks.
Demand in electric power and new energy industries is growing rapidly. Boiler flues, steam turbines and high-temperature air ducts of thermal power units have strict requirements on temperature resistance, fire resistance and low dust. The aerogel glass fiber blanket features Class A fire resistance and ultra-low thermal conductivity, avoiding material damage and shedding caused by high-temperature flue gas scouring. In photovoltaic power stations, energy storage stations and supporting facilities of new energy power generation, it is used for cabin insulation and fire separation, blocking the influence of external temperature changes and preventing heat spread, so as to improve the operation safety and stability of power equipment.
Rail transit and marine industries focus on light weight and weather resistance. The blanket is applied to equipment cabins and ventilation ducts of high-speed rails and subways. Its light weight effectively reduces vehicle weight, realizing energy saving and noise reduction. Ship decks, engine rooms and oil pipelines operate in environments with salt spray, high humidity and alternating temperatures. The material is hydrophobic, moisture-proof and salt spray resistant, adapting to harsh marine conditions. Its flexibility fits the narrow spaces and complex structures on ships.
In addition, it is widely used in industrial kilns, fire separation and special building insulation. Its application value is reflected in three aspects: energy conservation and carbon reduction by reducing heat loss; cost reduction and efficiency improvement by extending maintenance cycles; safety upgrade with high temperature resistance, fire resistance and low dust to optimize working environment. As energy-saving and safety standards are continuously improved in various industries, the market penetration of this material will keep rising and it will become the leading product in the high-end flexible insulation market.
