硬质聚氨酯泡沫广泛地应用于冰箱保温，发泡剂对于聚氨酯泡沫的保温效果起着至关重要的作用。人们越来越重视气候和环境问题，但是目前的常用发泡剂都有一些缺点。 CFC-11和HCFC-141b的臭氧损耗潜值不为零，正在被逐步淘汰，而HFC-245fa 、 HFC-365mfc这样的HFC类发泡剂的全球变暖潜值将近1000。聚氨酯领域正在寻找臭氧损耗潜值为零、全球变暖潜值很低的发泡剂。 LBA 和FEA-1100是非常有前途的发泡剂，将来可能会取代目前的常用发泡剂。

Rigid polyurethane foams are widely employed for thermal insulation in refrigerators. Blowing agents are critical for providing the insulation performance of these foams. Concerns over climate and environment have intensified, but current blowing agents all have defects. CFC-11 and HCFC-141 b is being phased out due to their ODPs. HFCs such as HFC-245 fa and HFC-365 mfc have GWPs near 1000. Polyurethane industry is seeking blowing agents not only with zero ODP, but also with lower GWPs. LBA and FEA-1100 are very promising blowing agents and they likely to replace current blowing agents in future.
