Glass fiber composite filter bag
Detailed introduction

Glass fiber composite filter bag:

The outstanding advantages of glass fiber are high temperature resistance, which can be used at high temperatures of 260-280 ° C, and good dimensional stability and high tensile strength, which is more than twice that of synthetic fiber filters. In terms of chemical resistance, except for strong acids such as hydrofluoric acid and high temperature and strong alkali, it is very stable to other media, but its disadvantage is poor folding resistance . It cannot be used to purify industrial furnace fumes with fluorite or HF acid.
