POLYURETHANE RESIN-FORMABLE COMPOSITION FOR RADIATION SHIELDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a polyurethane resin-formable composition for a radiation shielding material which is excellent in workability and provides excellent radiation shielding properties to a molded article.SOLUTION: A polyurethane resin-formable composition for a radiation shielding material contains polyol, polyisocyanate and an inorganic filler having a true specific gravity of 4.0-6.0. A polyurethane resin molded article for a radiation shielding material is obtained by reacting and curing the polyurethane resin-formable composition for the radiation shielding material, and molding the cured composition. A radiation shielding material is obtained by working the polyurethane resin molded article for the radiation shielding material.SELECTED DRAWING: None
