Silica Aerogel Market Size

Silica Aerogel Market size was over USD 1.5 billion in 2025 and is estimated to reach USD 3.1 billion by the end of 2035, expanding at a CAGR of 8.7% during the forecast timeline, i.e., 2026-2035. In 2026, the industry size of silica aerogel is assessed at USD 1.6 billion.

The international silica aerogel market is currently witnessing a transformative phase, evolving from a specialized and high-cost material, which is readily utilized in aerospace, to a mainstream industrial solution. Silica aerogel is considered the lightest solid material that comprises exceptional thermal insulation properties, and it is uniquely positioned to address a few of the world’s challenges. These include the safety of electric vehicles, sustainable construction, and industrial decarbonization. According to an article published by NLM in July 2023, aerogel has a thermal conductivity of only 0.02 W/(m·K)−1, along with an ambient temperature of 25 degrees Celsius, which is considered lower than static air at 0.025 W/(m·K)−1. Besides, SiO2-based aerogel includes 80% to 99.8% high porosity, 100 to 1,400 m2/g of high specific gravity, and low density ranging between 0.003 to 0.4 g/cm³, thereby making it suitable for bolstering the silica aerogel market globally.

Furthermore, product diversification, hybrid materials, increased focus on the Asia-Pacific supply chain, vertical integration for supply chain security, and the emergence of high-performance apparel are also fueling the silica aerogel market across different nations. In the case of supply chain security, notable players are increasingly backward-integrating into exporting raw materials to ensure quality, overcome logistical disruptions, and control expenses. In this regard, the March 2023 EPA Government article denoted that the domestic production accounts for 108,000 M kg, followed by 389 M kg as imports for consumption, and 5,540 M kg for export of domestic production. Besides, as per an article published by Construction and Building Materials in March 2025, the mortar samples’ flexural strength has been evaluated through a three-point bending evaluation, and samples with added 3%, 5%, and 7% silica aerogel constituted flexural strength of 2.22 MPa, 1.94 MPa, and 1.80 MPa. Therefore, the purpose is to ensure standard silica aerogel, which is positively impacting the overall market.
