MOISTURE-PERMEABLE POLYURETHANE, MOISTURE-PERMEABLE MOLDED PRODUCT AND MOISTURE-PERMEABLE TUBE

摘要

PROBLEM TO BE SOLVED: To provide a moisture-permeable polyurethane which has good moisture permeability and moldability and may be molded into, e.g. an extra-fine tube, and a moisture-permeable molded product and a moisture-permeable tube obtained from this. SOLUTION: The moisture-permeable polyurethane is obtained by using at least an isocyanate ingredient, a polyol as a chain extender and polyethylene glycol as a polyol ingredient as raw materials and allowing them to react with each other.
