HEAT INSULATING BOX USING RIGID POLYURETHANE FOAM

PURPOSE:To obtain a heat-insulating box having excellent heatinsulating property and adhesion without using regulated CFC but using a blowing agent compounded especially with fluorocarbons. CONSTITUTION:A starting mixture of polyol is composed of 20-70 pts.wt. of an aliphatic compound having average...
