PROBLEM TO BE SOLVED: To provide a flame retardancy polyurethane elastomer raw material composition that uses a flame retardant considering environmental harmony without using flame retardants of a halogen series such as bromine, chlorine; and to provide a molding that is formed by the same, in which a drip phenomenon is not caused in combustion, and that has an excellent flame retardancy that is effective to the control of flame and a smoke quantity.SOLUTION: The flame retardancy polyurethane elastomer raw material composition is made by making a polyurethane elastomer raw material include a composite flame retardant that consists of a ternary system of a first flame retardant that consists of a carbon series as a flame retardant, a second flame retardant that consists of a phosphorus series, and a third flame retardant that consists of linseed oil that is a plant origin. The molding excellent in flame retardancy is obtained by forming the flame retardancy polyurethane elastomer raw material composition. |
