The airgel thermal insulation felt industry has huge development potential, and building insulation materials are its main application areas.

Airgel insulation felt refers to a solid insulation material made of silica or metal airgel as the main material and compounded with carbon fiber, ceramic glass fiber wool or pre-oxidized fiber felt through a special process. Airgel insulation felt has the advantages of fire resistance, heat insulation, heat preservation, tensile strength, compression resistance, safety and environmental protection, etc., and is widely used in building insulation materials, aerospace, petrochemical and other fields.

The production methods of airgel insulation felt include sol-gel method and lamination sintering method. The sol-gel method refers to mixing the sol with a metal catalyst, and finally obtains the finished product through aging, graded replacement, surface treatment, drying and other processes; the pressed film sintering method uses silica powder as the main raw material, and is formed by pressing and Sintering and other steps to obtain the finished product. The thermal insulation performance of airgel insulation felt prepared by the lamination sintering method is relatively poor, but this method has the advantages of low production cost and high work efficiency, and is suitable for large-scale production.

The upstream of the airgel insulation felt industry chain supplies raw materials, and functional silane is its main raw material. my country is the world’s largest producer of functional silane. In 2021, my country’s functional silane production capacity will exceed 550,000 tons, accounting for 61.3% of the world’s total production capacity. Driven by the advantages of raw materials, my country’s airgel insulation felt production continues to increase. At the same time, thanks to continuous technological breakthroughs and innovations, the production cost of airgel insulation felt in my country continues to decline, which provides favorable conditions for the development of the industry.

According to the “2022-2027 China Airgel Insulation Felt Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that the downstream of the airgel thermal insulation felt industry chain is the application field, and building insulation materials are its main market. Traditional building insulation materials have shortcomings such as easy aging, poor insulation effect, short service life, and poor flame retardancy, and cannot meet market demand. With the gradual advancement of the country’s “double carbon” goal, green and environmentally friendly building materials are favored by a wide range of consumers. Airgel insulation felt has the characteristics of high flame retardancy, strong hydrophobicity, and excellent wind load resistance, and is expected to become a building insulation material. Market mainstream products. Driven by market demand, the market size of my country’s airgel insulation felt has expanded, and it has exceeded 3.50 billion yuan in 2021.

Global air gel’s heating felt leading companies include Cabot Cabot, American ASPEN AEROGELS, British Airgel UK, etc. The main manufacturers of airgel insulation felt in my country include Foshan Jinyinhe Intelligent Equipment Co., Ltd., Jiangsu Huachang Chemical Co., Ltd., Shanxi Huayang Group New Energy Co., Ltd., etc. Industry analysts said that thanks to the support of national policies, the prosperity of my country’s airgel insulation felt industry continues to improve, and in building insulation materials The field has broad application prospects. Driven by technological innovation, my country’s airgel insulation felt production continues to grow, and high-end development will become the mainstream trend in the future development of the industry.
