Low-Free Prepolymer (CPU), also known as low free isocyanate polyurethane prepolymer, is a key raw material for polyurethane elastomer casting systems. Compared with traditional polyurethane prepolymers, low-free CPU prepolymers contain extremely low residual isocyanate, providing safer handling, better processing stability, lower odor, and improved mechanical properties.
Shandong Beiqiao New Material Technology Co., Ltd. is a professional low-free prepolymer manufacturer and supplier in China, offering a complete range of PPDI prepolymers and TDI prepolymers for global PU elastomer producers.
Our low-free polyurethane prepolymers are widely used in PU wheels, PU rollers, polyurethane elastomers, industrial seals, wear-resistant parts, mining screens, and casting polyurethane products.
