Since polyurethane production is actually a process of chemical reaction control, its reaction rate is very important. Different products, different processes and different formulations have different requirements for the reaction rate. Taking a reasonable response rate that adapts to needs plays an......
Read MoreAs the main auxiliary agent for polyurethane foaming, color paste is widely used in various types of polyurethane materials. As a professional polyurethane color paste manufacturer in East China, the color paste produced by our factory has the characteristics of high color concentration, good fluidi......
Read MorePolyurethane adhesive has excellent rubber properties and can adapt to the adhesion of substrates with different thermal expansion coefficients. It forms a soft-hard transition layer between the substrates, which not only has strong adhesion, but also has excellent cushioning and shock absorption. F......
Read MoreIn order to more accurately select the shrinkage rate of large cast polyurethane elastomer products, the influence of process conditions, environmental factors and product structure on the shrinkage rate was systematically studied, and the shrinkage rate versus time curve was measured. The reasons a......
