Abstract
Disclosed herein is a method of producing a filter medium for treating medium and high temperature exhaust gas using foam coating and a filter medium produced using the method. The filter medium has excellent heat resistance and heat contraction resistance, and exhibits partial dust collection efficiency of 99% or more by weight, total dust collection efficiency of 99.999% or more by weight, and high dust removal efficiency, for all dust particle sizes. Further, the filter media can be efficiently used to treat medium and high temperature exhaust gas because pores having an average pore size of 30 μm or less are uniformly distributed on the surface of the filter media.
