摘要： A mixture of CFC-113 and CFC-123 and/or CFC-123a where CFC-123 or CFC-123a is a significant portion of the total composition has been found to result in improved blowing agent performance in phenol-formaldehyde foams compared to CFC-113.The use of CFC-123 (or CFC-123a, or both), in combination with CFC-113 improves resole resin solubility and mixed ingredient solution stability, prior to foaming. In addition, because of the lower molecular weight of CFC-123 (or CFC-123a) compared to CFC-113 better blowing agent efficiency will be realized per unit weight. Also, the lower boiling points of CFC-123 and CFC-123a as compared to CFC-113 results in a more ready conversion of dissolved blowing agent to released gaseous blowing agent by the exothermic phenolic resin polymerization. And because of the lower molecular weight and lower boiling point factors, a lower density foam is realized.

摘要翻译： 发现CFC-113和CFC-123和/或CFC-123a的混合物，其中CFC-123或CFC-123a是总组合物的重要部分，与CFC相比，发现苯酚 - 甲醛泡沫中的发泡剂性能得到改善 -113。 与CFC-113组合使用CFC-123（或CFC-123a或两者）可以在发泡前提高树脂的溶解度和混合成分溶液的稳定性。 另外，由于与CFC-113相比CFC-123（或CFC-123a）的分子量较低，因此每单位重量可以实现更好的发泡剂效率。 此外，与CFC-113相比，CFC-123和CFC-123a的较低沸点导致通过放热酚醛树脂聚合将溶解的发泡剂更容易地转化为释放的气态发泡剂。 并且由于较低的分子量和较低的沸点因素，实现了较低密度的泡沫。

摘要： Improved fluorocarbon blowing agents composed of blends of (a) CFC-11, trichlorofluoromethane, with (b) CFC-123 or CFC-123a, dichlorotrifluoroethane, have been found which impart significant improvement in the solubility characteristics of rigid urethane foam systems that contain significant amounts of aromatic polyester polyols. A substantial increase in the solubility of the CFC-11/CFC-123 or CFC-11/CFC-123a blends over CFC-11 alone in typical rigid urethane foam premix systems containing variable concentrations or aromatic polyester polyol is obtained. Preparation of rigid urethane foams have shown that improved solubility CFC-11 blends with CFC-123 or CFC-123a permit an increase in the amount of aromatic polyester polyol than can be used in the formulation without any significant differences in the physical characteristics of foams compared to those produced from CFC-11 without inclusion of aromatic polyester polyols.
