| titleOfInvention | Foaming system for phenolic foams |
| abstract | 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. |
