Ammonia ester bond is composed of isocyanate and hydroxy reaction gain. Castor oil because of its contain many hydroxy component, rich sources and low price for the production of polyurethane (pu) provides plenty of raw materials. This report by castor oil as raw material, the feasibility of the annual capacity of 450 tons of polyurethane, mainly from the project market analysis, project construction scale and investment plan, production technology and equipment, raw materials and fuel power, engineering construction plan, environmental protection, safety, energy saving, investment estimation and financing, economic benefit analysis, are discussed. With castor oil polyurethane is divided into castor oil alcohol solut
