Glass fiber needle felt and glass fiber composite needle felt

Glass fiber needle felt and glass fiber composite needle felt

The product characteristics of the glass fiber needle felt and glass fiber composite needle felt produced by our company are:

Features

    • Can withstand high temperatures above 260 ℃, instantaneous temperature can reach 300 ℃. It has good oxidation resistance and can adapt to acidic environment.
    • High-temperature composite needle punched felt is made of glass fiber mixed with corresponding high-temperature resistant chemical fiber according to the operating temperature and chemical properties of flue gas under different working conditions. While meeting the strict temperature and chemical requirements of the filter media under working conditions, it also significantly reduces the material cost compared with pure high temperature chemical fiber needle felt. Has outstanding performance and economic benefits.
    • After special needle punching and post-treatment, the glass fiber needle punched felt has excellent temperature resistance and excellent filtration performance, and is widely used in high temperature flue gas filtration in cement kilns, steel making, and metallurgy.
