In recent years, with the implementation of the "carbon neutrality" strategy and the upgrading of high-end manufacturing, the market's requirements for insulation and heat preservation materials have become increasingly higher - not only do they need to have good insulation performance, but also be lightweight, flame-retardant, flexible, and durable. Traditional insulation materials are gradually unable to meet these demands. Against this backdrop, pre-oxygenated aerogel has emerged. As a "all-round" new composite material, it breaks the performance limitations of traditional materials and has become a "new trend" in the new materials industry. Today, we will introduce to you in detail what pre-oxygenated aerogel is and how it breaks industry bottlenecks and empowers the development of various industries.
First of all, we need to clearly understand a core concept: Pre-oxygenated aerogel is not a single material, but rather a "superior fusion" of two high-quality materials. It is a new type of composite insulation material developed by Iota to address the industry's pain points of traditional aerogels being "fragile and difficult to use" and traditional insulation materials having "poor insulation, being heavy and cumbersome". Its core composition is "pre-oxygenated fiber substrate" and "silicon dioxide aerogel". The scientific combination of these two materials enables this new material to achieve a performance breakthrough of "1 + 1 > 2", solving industry pain points and expanding application scenarios. This is also the core reason for its rapid rise.
When analyzed in detail, the pre-oxidized filament serves as the reinforcing base material, being a fiber material made from polyacrylonitrile through pre-oxidation treatment. It possesses core advantages such as high temperature resistance, flame retardancy, and tensile strength. Its maximum temperature resistance can reach 450℃, and its fire resistance rating is A-level non-combustible, non-flammable, and non-melting droplets. It can provide stable structural support for aerogel. Meanwhile, the silica aerogel, as the core of insulation, is hailed as "the lightest solid in the world", with a porosity of over 90%, and a thermal conductivity as low as 0.023W/m·K. Its insulation performance far exceeds that of traditional rock wool and glass wool, but its own texture is fragile and prone to cracking, and it cannot be used alone in actual production scenarios.
Aiyota successfully broke through this industry bottleneck through its independently developed nano-composite technology. The aerogel was evenly penetrated and adhered to the gaps between the pre-oxidized fiber strands. After undergoing multiple precise processes such as modification, supercritical drying, and compression molding, the two materials were perfectly integrated. The final pre-oxidized fiber aerogel not only fully retained the super-strong insulation and lightweight characteristics of the aerogel, but also overcame the weakness of the aerogel being fragile by leveraging the supporting effect of the pre-oxidized fibers. It simultaneously possessed the advantages of flexibility, ease of processing, corrosion resistance, and durability. It can be freely cut, bent, and is suitable for various complex construction scenarios. No special equipment is required, significantly reducing the application threshold.
Compared with traditional insulation materials, the core competitiveness of pre-oxygenated aerogel better meets the current industry upgrading needs. In today's context where the "dual carbon" strategy is being vigorously implemented, the fields of construction, industry, and new energy have increasingly strict requirements for energy conservation and consumption reduction. Pre-oxygenated aerogel, with its extremely low thermal conductivity, can effectively reduce heat loss and help enterprises lower energy consumption and save costs. For example, after being used in industrial pipelines, it can reduce heat loss by more than 30%, and when applied to building exteriors, it can reduce air conditioning energy consumption by 25%.
Meanwhile, its A-level non-combustible property and the absence of toxic or harmful substances release also meet the safety and environmental protection requirements of various industries. In the field of new energy, it is used for heat insulation in battery packs, effectively preventing the risk of thermal runaway; in the construction industry, it is used for exterior wall insulation, which can enhance the fire resistance of buildings and ensure the safety of residents; in high-end fields such as aerospace and petrochemicals, it can be applied to achieve stable heat insulation protection in extreme environments.
As a veteran player in the new materials industry, Iota not only achieved large-scale production of pre-oxygenated silk aerogel, but also continuously innovated technologies, optimized production processes, and reduced product costs. This way, this "black technology new material" has moved from the high-end sector to civilian industries and daily life scenarios. Currently, Iota's pre-oxygenated silk aerogel has reached cooperation with several leading enterprises in various industries and is widely applied in building energy conservation, new energy vehicles, industrial insulation, and other fields.
