Research and application of secondary reaction effect on polyurethane foaming elastic pad
There is still a secondary reaction after the first pouring completely and demolding of the polyurethane material.This phenomenon has a significant effect on the judgment of polyurethane production,testing,application,etc.In view of the polyurethane microcellular foaming elastic pad products,the influence of varying the secondary reaction temperature and time on the size and stiffness of the products after pouring and molding of polyurethane foaming materials was mainly investigated.The variation rules of the size and stiffness of the products with the above conditions were investigated,and the optimal secondary reaction conditions were summarized.
