Customized polyurethane elastic prepolymer reactor 50L-5000L | Feilong Equipment Manufacturer | Laboratory/Industrial use YJF-（series）
APPLICATION:The prepolymer method involves conducting the chain extension reaction (prepolymer reaction) and the chain extension-crosslinking reaction in two separate steps during CPU production. This allows the highly reactive reaction (the prepolymer reaction between polyols and isocyanates) sufficient time to proceed more thoroughly. The resulting prepolymer then reacts with the chain extender, producing an elastomer with a uniform structure. This facilitates the formation of hydrogen bonds between the hard segments of the polyurethane macromolecules, as well as between the hard segments and the strongly electronegative groups in the soft segments. As a result, the product exhibits excellent mechanical properties and good reproducibility. This equipment serves as a specialized prepolymer reaction vessel for the aforementioned method.
Product Details
FEATURES
1.The system features a scientifically designed process flow and comprehensive configuration, capable of automatically controlling material temperature according to process requirements. It achieves rapid and uniform heating as well as quick and convenient cooling.
2.The reactor employs an advanced structural design with a high-performance dynamic sealing system for the stirring shaft, ensuring excellent vacuum maintenance during mixing operations. It incorporates Germany's advanced bottom discharge valve technology, which minimizes residual material at the reactor bottom, resulting in more complete reactions and more convenient, reliable operation.
