低CFC发泡工艺

Polyurcthane Rigid Foams Using a Small Amount of CFC

介绍了减少75％CFC－11的聚氨酯硬质泡沫塑料的发泡工艺，对影响工艺参数和泡沫性能的一些因素进行了讨论。该泡沫的密度与导热系数较全CFC－11发泡泡沫均增大15％～20％。

The manufacture of Polyurethane rigid foam blown with 75% reduced CFC--11 is described. The influences on process and properties of foams are discussed. The density and thermal conductivity of this rigid foam increased by 15 percent to 20 percent.
