Polyurethane is a polymer material with good elasticity and wear resistance, widely used in various fields. It is generated by the reaction of isocitrate and polyol, with isocitrate being the main reaction component and polyol being the secondary reaction component. The performance of polyurethane depends on the type and proportion of isocyanate and polyol, as well as the reaction conditions. Polyurethane can be divided into hard polyurethane and soft polyurethane. Hard polyurethane is mainly used for building insulation and waterproofing, while soft polyurethane is mainly used for furniture and footwear manufacturing. The production process of polyurethane includes steps such as reactor reaction, mixing, foaming, and molding. Polyurethane has excellent performance, but safety should be taken into account during the production process to avoid the production of harmful substances.
