Fiberglass Filter Bag: Reliable 260°C Dust Filtration

fiberglass dust filtration bags withstand a continuous 260°C and are non-combustible with high tensile strength — a far more affordable high-temperature option than PTFE for cement kilns and carbon black plants; however, their brittleness and poor flex/abrasion resistance require careful handling, and they are not suitable for HF or strong alkali gases.
