High temperature resistant and heat insulation fiber felt is made of high-purity synthetic material instead of traditional natural material. It is made by special continuous melting and continuous spinning process. It has higher temperature for long-term use. The product has the advantages of high tensile strength, low thermal conductivity and low heating wire shrinkage. Compared with similar products, it has 1 / 3 greater fire resistance, heat insulation and energy saving effect. The product is white in color and regular in size. It has the functions of fire resistance, heat insulation and heat preservation, and does not contain any bond. It can maintain good tensile strength, toughness and fiber structure when used in neutral and oxidizing atmosphere. The thermal and physical properties can be recovered after drying. Compared with its corresponding fiber cotton, it has the same excellent chemical stability, higher strength at room temperature and after burning, and can be widely used It is widely used in the fields of fire resistance, heat insulation and heat preservation.
