Reinforcing Polyol Improves Strength at Low Density

配方组成:

$G: "Pluracol" PEP-450
Within the effective proportions, incorporation of "Quadrol"
improves cell structure, content of closed cells, and retention of "K"
factor. The formulation with 80 to 20 ratio provides foam that is
technically and economically practical

配制方法:

To obtain maximum strength in low-density foams, it is desirable to use a dry resin with the minimum hydroxyl functionality of three. With resins that do not fit in this category, useful foams can be obtained by adding a reinforcing resin such as "Quadrol."
