Fiberglass needle punched felt is a superior filtering material with high porosity, low gas filtration resistance, high filtration wind speed, high dust removal efficiency, as well as characteristics such as bending resistance, wear resistance, and dimensional stability.

Main purpose:

Fiberglass needle punched felt can be used for sound insulation, sound absorption, shock absorption, flame retardancy, etc. in the automotive industry, mainly in the filtration field of industry; Fiberglass needle punched felt is widely used for flue gas purification and dust recovery in industries such as carbon black, steel, non-ferrous metals, chemical, and incineration.

Operating conditions:

1. The working temperature of fiberglass needle punched felt should be less than 260 ℃.

2. Alkali free glass fiber expanded filter material is applied in the technology of Nanjing Fiberglass Institute, using German imported expansion equipment to produce fully expanded or two-thirds expanded filter cloth (bag). The organization has double satin weave, diagonal weave, etc.

3. The product specifications of alkali free glass fiber expanded through fabric (bag) are Ø 120-300mm, which has the performance of ordinary glass fiber through materials. At the same time, after high-temperature hot washing, the fabric group is slightly reinforced, the wear resistance is increased, the filtration wind speed is increased, and the service life is greatly improved.

Main purpose:

Alkali free expanded glass fiber filter cloth (bag) is widely used for dust and gas filtration in industries such as steel, power, metallurgy, chemical, environmental protection, and cement.

Operating conditions:

Long term use should be between 200 ℃ and 280 ℃, with a preferred operating temperature of 90 ℃ to 220 ℃. The working temperature of FCA formula should be less than 180 ℃; The filtering wind speed should be less than 0.8m/min.

The company selects imported and domestically produced high-quality long filament polyester fibers, short filament polyester fibers, and produces various widths of polyester needle punched filter media to meet all customer needs in dust filtration and liquid filtration.

Polyester needle punched felt, as a widely used filtering material, has good cost-effectiveness and a long service life. Under the relevant working conditions, our company provides the produced polyester needle punched felt filter bags.
