Polysiloxane materials reshape the landscape of building energy conservation and industrial protection

1.Material innovation in the field of building energy conservation: Dual breakthroughs in insulation and safety
The global market size of silicone insulation materials is expected to reach 45 billion yuan in 2025, with the Chinese market accounting for more than 35%, making it the world's largest consumption region. Nano-modification technology has driven a significant leap in material performance. The thermal conductivity of the new polysiloxane insulation material has dropped below 0.022W/(m · K), and its fire resistance rating generally meets the A2 standard. Its penetration rate in the external wall insulation system of super high-rise buildings has reached 62%. The intelligent temperature-regulating polysiloxane board realizes the molecular-level composite of phase change materials and silicon-based carriers, with a temperature regulation range of up to 20℃. It is expected to form a scale of 1.2 billion yuan in the passive building market by 2025. Driven by policies, the upgrading of green building standards has led to a sharp increase in high-end demand, and the average annual growth rate of this sub-sector is expected to exceed 18%.

2. Upgrading of industrial protective materials: The performance advantages of silicon-based fabrics have become prominent
The global silicon-based fabric market is showing strong growth. The market size was 5.24 billion US dollars in 2024 and is expected to reach 7.73 billion US dollars in 2033, with a compound annual growth rate of 4.43%. This type of material, with its excellent resistance to extreme temperatures, ultraviolet rays and chemical inertness, has become the preferred choice for hazardous environmental protection. In the field of fire protection, protective equipment made of polysiloxane-coated fabric can withstand temperatures above 300℃ and has passed the NFPA flame retardant standard certification. The new energy vehicle industry is driving demand upgrading. The application of silicon-based fabrics in battery insulation and cable sheaths is growing at an average annual rate of over 15%, and their lightweight characteristics can reduce the weight of the entire vehicle by approximately 3%.

3. Iteration of building sealing technology: Enhanced long-term waterproofing and environmental protection performance
The market for polysiloxane sealants used in construction continues to expand. The global scale reached 5.21 billion US dollars in 2024 and is expected to increase to 6.57 billion US dollars in 2028, with a compound annual growth rate of 5.97%. Under the trend of green buildings, the proportion of water-based polysiloxane sealing materials has increased to 60%, and the VOC emissions are reduced by more than 70% compared with traditional products, meeting the strict requirements of the EU REACH regulation. In the joint sealing of high-rise building curtain walls, silicone rubber foam materials have taken the leading position due to their excellent resilience and weather resistance. The global market size reached 7.8 billion yuan in 2024 and is expected to exceed 9.2 billion yuan in 2025.

4. Technological innovation drives market expansion: From construction to emerging fields
Polysiloxane materials are developing towards multi-functional integration. After hydrophobic modification of aerogel felt, the thermal resistance retention rate exceeds 90% in a 95% humidity environment. It is expected that the application scale of cold chain logistics will exceed 1.5 billion yuan by 2025. Innovation in production processes has driven down costs. The vapor deposition method has reduced the production cost of aerogel to below 800 yuan per square meter, accelerating its commercial application. The regional market pattern has been optimized. The proportion of new production capacity in China's central and western regions has increased from 18% in 2022 to 30% in 2025, and the proportion of exports is expected to rise to 20% of the total output. The green building market in Southeast Asia has become a major growth point.
