Fiberglass Needle Punched Felt
Fiberglass Needle Punched Felt is a three-dimensional porous non-woven material manufactured from fiberglass via non-woven processes including opening, carding, web laying and needle punching.
Its fibers are randomly interlaced to form a stable microporous structure. The product features high temperature resistance, corrosion resistance, flame retardancy, electrical insulation, sound absorption, shock absorption and excellent dimensional stability. Containing no adhesive, it is eco-friendly and non-toxic, with low filtration resistance, high dust removal efficiency and superior high-temperature tolerance.
It is widely used for high-temperature flue gas filtration in iron and steel, chemical, waste incineration and other industries, as well as for equipment thermal insulation, electrical insulation, sound absorption and noise reduction applications.
- Product Introduction
Products Description
Fiberglass Needle Punched Felt is a high-performance filter material produced with advanced needle-punching processes using fiberglass as the primary raw material. Countless fiberglass filaments are interwoven via repeated needle punching to form a three-dimensional fluffy structure that delivers excellent filtration precision and dust holding capacity.This material features exceptional temperature resistance, with a softening temperature of 850°C and a tensile strength up to 350 kg/mm². It also possesses great chemical stability, allowing long-term stable operation under a wide range of harsh working conditions. Multiple surface post-treatments including membrane lamination, singeing and impregnation are available on demand to further enhance filtration efficiency and service life.For optimal performance, the working environment should maintain a temperature of 15°C to 35°C and relative humidity ranging from 30% to 70%. It is extensively used for dust removal and flue gas purification in iron and steel, cement, chemical and waste incineration industries, acting as an indispensable core filter medium in modern industrial environmental filtration.
