Shenzhen Petersburg Composite Materials Co., Ltd

High-silica needle felt is an inorganic thermal insulation material made of high-purity high-silica glass fiber. It has excellent high-temperature resistance and long-term structural stability and is widely used in thermal protection systems under extreme working conditions. Its continuous operating temperature can reach 600°C and its peak temperature resistance can reach 800°C. It can still maintain good mechanical strength and thermal insulation performance under high temperature conditions, and is suitable for complex industrial applications that require long-term thermal management. The material has excellent chemical stability, acid and alkali corrosion resistance, non-combustible, non-toxic and environmentally friendly, and meets the stringent requirements of modern industrial and aviation standards for high-reliability thermal insulation materials. The flexible felt structure is easy to cut, wrap and customize, and can provide a variety of thicknesses and sizes to meet the technical requirements of different equipment structures and installation environments. Common applications include thermal insulation and heat shielding systems in the aerospace field, high-temperature protection of petrochemical and refining equipment, automotive exhaust systems and engine thermal management, thermal insulation protection of power plant boiler systems, and thermal insulation layer design for household and commercial appliances. In these high heat load environments, high-silica needle felt provides stable, efficient and long-lasting thermal protection performance, and is an indispensable thermal management solution for critical systems.
