Patent number: 11970566Abstract: 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.Type: GrantFiled: September 30, 2022Date of Patent: April 30, 2024Assignees: HYUNDAI TRANSYS INC., CHIN YANG CO., LTD.Inventors: Jae Yong Ko, Seung Keon Woo, Young Tae Cho, Won Sug Choi, Sung Yoon Lee, Jae Kwang Lee, Jun Ho Song
