Open-celled semi-rigid foams with exfoliating graphite |
摘要 |
A method for producing an open cell low-density semi-rigid polyurethane foam suitable for general use as a thermal insulating material and/or an acoustical applications is disclosed. The method comprises a method for producing a flame-retardant open-celled semi-rigid polyurethane foam having an overall density of 5 to 30 kg/m2 by reacting (a) a polyisocyanate and (b) a polyol having a molecular weight of 100 to 10,000, in the presence of (c) an effective amount of an exfoliating graphite, (d) blowing agent and (e) optional additional auxiliary substances to produce.
