苯酐聚酯多元醇在聚氨酯硬泡中的应用

The Application of Benzolic Acid Anhydride Polyester Polyols in Polyurethane Rigid Foam

通过选择或合成聚醚多元醇，调整聚氨酯泡沫配方，介绍了苯酐聚酯多元醇在聚氨酯硬泡中的应用。实验证明，泡沫性能良好，泡沫稳定剂使用量减少，泡沫成本大幅度下降。

By selecting or synthesising polyether polyol, and changing rigid foam formulations, the application of benzoic acid anhydride polyester polyols in polyurethane rigid foam is introduced in this paper. Experiments show that properties of the rigid foam are good, because decrease in the quantity of foam stabilizer, the cost is low.
