Basalt fiber needled felt is made by random entanglement of single fibers to form a three-dimeasional structure.Because of the Iarge surface area of 7-9 μm fine fibers and about 80%porosity,basalt fiber needled felt can be used in high efficiency air filtration and purification,heat and sound insulation,and used as cushion material for hot rolIing of steel and aluminum.
