Fibergalss Needle-punched felt is a kind of composite fiber filter material. It is mainly composed of glass fiber, P84 (polyimide) fiber, aramid (aromatic polyimide) fiber, PTFE (polytetrafluoroethylene) fiber and other high-temperature materials. The needle-punched felt is made into felt. After finishing, PTFE emulsion is used as the main chemical compound treatment solution. After high-temperature setting impregnation treatment, the surface of the product is smoother and smoother. It is good for ash cleaning, and gives the product a certain acid and alkali corrosion resistance. The appearance feels soft and hard moderately. The product has the characteristics of high strength, low elongation, good air permeability, large air permeability, low operating resistance, 3-4mm thickness, high temperature resistance 250 C, good acid and alkali resistance, wear resistance, flexure resistance, water and oil resistance. Flumex needle-punched felt is conducive to the capture of high-temperature flue gas dust, with high filtering accuracy and filtering effect of 99.99%. Flumex needle-punched felt is a low resistance and high efficiency multi-functional filtering product.
