  • Patent number: 11970566
    Abstract: Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.
