1. Overview Polyurethane prepolymer is a reactive intermediate with carbamate group in its skeleton, which is obtained by the reaction of polyisocyanate and polyol. It is widely used in many fields, such as polyurethane adhesive, coating, elastomer, foam and fiber. The Puranate series hydrophilic prepolymer of jiahua chemistry is a reactive liquid blocked by...

Introduction Polyurethane viscoelastic foam, also known as memory foam and low-resilience polyurethane (LRP), was developed for airplane cushions by NASA. At the end of the last century, it was commercialized by a multitude of polyurethane manufacturers and gradually entered ordinary consumers’ life. The mechanism of conventional VE foam lies on its mechanical characteristics that the...

Modified MDI, as a derivative of MDI series products, is a technical extension of pure MDI and polymerized MDI products commonly used in the market at present. It mainly relies on MDI's own reaction or reaction with other chemicals and mixing with other chemicals to obtain the best viscosity and functionality products, which are widely used in soft foam, elastomer, coating, adhesive and other...
