Discussion on the Flame Retardant Technology of Polyurethane Thermal Insulation Materials

Rigid polyurethane foam insulation materials belonged to the organic polymer insulating material,and the thermal conductivity of insulation materials was the lowest of all and had the most superior thermal performance.The combustion process of polyurethane thermal insulation material was introduced,and the flame retardant methods of rigid polyurethane foam insulation materials and its development trend were elaborated.
