Polyurethane elastomer from China manufacturer and its preparation method, the raw material composition of the elastomer includes Mannich polyether, isocyanate, which is obtained by mixing the Mannich polyether with a catalyst, and adding the isocyanate under constant stirring It is obtained by reacting, defoaming and curing after the reaction is completed. The elastomer formula provided by the present invention contains Mannich polyether components, which can catalyze the polyurethane reaction because of nitrogen atoms in the structure. Therefore, The introduction of Mannich polyether components increases the reactivity of the system, accelerates the progress of the polyurethane reaction, effectively reduces the amount of heavy metal catalysts, and reduces environmental toxicity and biological toxicity; by adjusting the amount of Mannich polyether, The hardness of the Polyurethane elastomer from China manufacturer can also be adjusted, and the flame retardancy of the Polyurethane elastomer from China manufacturer can be improved. The preparation method of the elastic ligand provided by the invention has simple operation, short cycle and low cost, and is suitable for large-scale popularization and application.

The above is a brief introduction to the knowledge of Polyurethane elastomer from China manufacturer and preparation methods.
