Title:
POLYURETHANE RESIN FOR BREATHABLE WATERPROOF RESIN, AQUEOUS DISPERSOID FOR POLYURETHANE RESIN FOR BREATHABLE WATERPROOF RESIN, SHEET MATERIAL AND MOISTURE-PERMEABLE WATER-PROOF FABRIC
Document Type and Number:
Japanese Patent JP2022065645
Kind Code:
A
Abstract:
To provide a polyurethane resin for breathable waterproof resins having reduced water swellability compared with conventional resins.SOLUTION: A polyurethane resin for breathable waterproof resins includes a polyether polyol having an oxyethylene group and an oxytetramethylene group (A) and an organic isocyanate (C) as constituent materials. The content of the polyether polyol (A) in the constituent materials is 40 wt.%-90 wt.% relative to the content of the constituent materials. Preferably the polyether polyol (A) is insoluble in water.SELECTED DRAWING: None
