High Temperature Filter Material – Glass Fiber Needle-Punched Felt

 

Glass Fiber Needle-punched Mat is a filter material with reasonable structure and good performance. It uses glass fiber as raw material, uses a needle to needle-punch the combed short-cut glass fiber mat, and uses mechanical methods to entangle the fibers between the mat layer glass fiber and the reinforced glass fiber base cloth, so that the fiber net is reinforced to form a mat-like non-woven filter material.

 

It not only has the advantages of glass fiber fabrics such as high temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and shrinkage, and high strength, but also the mat layer fibers are single fibers, three-dimensional microporous structure, high porosity, and low gas filtration resistance. It is a high-speed and efficient high-temperature filter material. Compared with other high-temperature resistant chemical fiber mats, it has special advantages such as low price and higher temperature resistance, but its running resistance is higher than that of general chemical fiber high-temperature filter materials.

 

The main characteristics of glass fiber needle-punched mat are: good thermal insulation, no combustion, good sound absorption, high insulation, high corrosion resistance, good recovery, low moisture absorption, light weight and softness, and easy construction.

 

Glass Fiber Needle-Punched Mat can be used for sound insulation, sound absorption, shock absorption, flame retardancy, etc. in the automotive industry. It is mainly used in the field of industrial filtration; high-temperature flue gas filtration; glass fiber needle mat is widely used in various bag dust collectors for flue gas purification and dust recovery in carbon black, steel, non-ferrous metals, chemicals, incineration and other industries.
