High silica needled Mat is made of high -silica glass fiber chopped yarns as raw materials, combed into a net by special equipment, and layered and needle-punched. A variety of industrial ultra-high temperature, automotive exhaust systems and other fields of thermal insulation, the products can be divided into two series of standard type and per-sintering.

　　The products are mainly used in: carbon black, steel, non-ferrous metal processing, chemical industry and other fields as filter material, high temperature heat insulation material, and also used as heat insulation material for high temperature protective cover, commercial vehicle exhaust pipe heat insulation, three-way catalysis heat insulation, etc.
