Glass fiber needle felt is a high-performance insulation material based on alkali-free glass fiber and processed by needle punching process. It has good mechanical strength, high temperature resistance and thermal insulation performance, and is a basic insulation material commonly used in thermal protection of modern industry and household appliances.

The material has a dense and uniform structure and good dimensional stability and heat resistance. The conventional operating temperature range can reach 550℃, and the short-term tolerance temperature can reach up to 700℃. It can maintain shape and strength in a long-term high temperature environment without deformation or shrinkage. Low thermal conductivity makes it an effective insulation layer in thermal energy management, which can significantly improve the thermal efficiency of equipment and protect surrounding components from thermal damage.

Because glass fiber itself has excellent corrosion resistance and moisture resistance, needle felt can adapt to oil, humidity and some acid and alkali environments, and is suitable for use in a variety of industrial environments. Its natural flame retardant properties also provide reliable protection for safe use. It meets Class A fire protection standards and does not support combustion or melt.

In terms of sound absorption and noise reduction, the porous structure of glass fiber needle felt can effectively absorb mechanical vibration and air noise, which helps to improve the acoustic environment during equipment operation, especially suitable for scenes where noise needs to be controlled.

In addition, the material does not contain asbestos, is safe and non-toxic, and meets environmental protection requirements. It is soft in texture, easy to cut and process, and can be customized in different sizes and thicknesses according to specific application requirements, adapting to the installation requirements of various complex structures and spaces.

Common applications include thermal insulation protection of household appliances such as ovens, water heaters, microwave ovens, and induction cookers. It is also widely used in industrial furnaces, pipelines, lining insulation of thermal equipment, and insulation layers of electrical equipment. It is an economical and practical thermal protection solution in high temperature environments.

This glass fiber needle felt is the preferred thermal insulation material in various industrial thermal management systems and household high-temperature equipment due to its excellent thermal insulation performance, structural stability and environmental protection characteristics.
