本篇文章论述了一种新型的发泡工艺。该工艺采用一个可加压的模具。它可以消除HFC-134a发泡过程中产生的泡沫空洞。这种技术可降低导热系数7%左右。泡沫的流动性也得到大幅度的改善，恰填量可降低10%左右。这主要是因为留在泡孔内的HFC-134a增加了。测试表明，留在最终泡孔内的HFC-134a增加了20%。实验结果同时表明，采用HFC-245fa或异丁烷发泡时，也可得出类似的结果。
This paper describes a processing technique that provided improved foam properties when compared to standard foaming techniques. The process innovation involved the use of a pressurized foam mold. This technique eliminated the blowholes from foam blown with HFC-134a. When using polyol blends that have been optimized for HFC-134a, the improvement in foam quality resulted in k-factor improvements of about 7%, or 0.01 BTU-in/hr-°F-ft². Minimum fill weights showed reductions of 10%. These improvements are due to the increased retention of the HFC-134a. Measurements confirmed a 20% increase in the amount of HFC-134a that remained in the final foam. Similar improvements were seen with HFC-245fa, as well as isobutane systems.
