What are the applications of glass fiber needled felts?

1.Industrial filter material field

  With the development of modern industry, the requirements for environmental cleanliness are getting higher and higher, thus the need for high efficiency filter material is more urgent. As needle felt has the characteristics of small pore size, high void ratio and zigzag internal path, the gas treatment capacity of needle felt can be up to 2-3 times that of woven filter media.

  In the process of air filtration, in addition to the dust particles being captured when entering the fiber layer, a layer of dust (dust cake) can be formed on the surface of the filter felt, which itself plays a highly efficient filtration role. Woven filter media depends on this role to a large extent, and needle felt, in addition, in its own structure has this function, and in the dust surface can be organized into a dense state, easy to use strong cleaning methods.

  Based on the structural characteristics of the needle felt filter media, it can be made to have: in the filtration of solid particles, low fluid resistance, fast filtration speed, high dust-catching efficiency, large capacity, size stability and other excellent performance, so that it is gradually replacing the traditional filter media in many aspects.

  At present, glass fiber needle felt has been widely used in carbon black, iron and steel, non-ferrous metals, chemical industry, incineration and other industries, and has achieved considerable economic benefits and social benefits recognized by the public. At home, industrial filtration material is the main application field of glass fiber needle felt.

2. Automobile industry

  Glass fiber needle felt is used in automobile interior decoration, as well as sound-absorbing, heat-insulating, shock-absorbing, flame-retardant and so on, which is a big market, and it contributes to the lightweight of the automobile and the effective use of space.

  Compounded with recycled fibers, glass needle felt can be used as roof and door gaskets, engine hoods (adhered to the inside), partitions between the engine and the compartment, and luggage compartment liners. These liners can play a role in heat insulation, sound absorption, shock absorption, flame retardant and so on.

3. Other fields

  Using the microporous nature of the needle felt has the effect of heat preservation and insulation, it can be used for pipeline heat insulation of various heat generating devices.

  The filtration and sound-absorbing effect of glass fiber needled felt can be used in the muffler and dust collector of automobiles and motorcycles.

In addition, glass fiber needle felt can also be used for geotextiles, coated fabrics, insulating materials and so on.
