戊烷发泡剂：戊烷作为发泡剂主要是给聚氨酯和苯乙烯发泡。戊烷发泡剂中戊烷主要为正戊烷和异戊烷且占比达到99%以上时可做苯乙烯发泡剂，成品eps，主要的机构如见龙机构等；此外正戊烷可用于建筑板材的发泡。做聚氨酯发泡剂时主要是环戊烷，主要用途是冰箱门体的泡沫~回家看看你家冰箱上可能就贴着环戊烷的标签~~这个主要是因为以前用佛利昂发泡造成臭氧层空洞嘛，后来换成了141b这样的，但是仍然有污染，戊烷就不会了，都是清洁产品。戊烷密度低，在0.62左右，易燃易挥发，作发泡剂就是利用它易挥发的特性，在苯乙烯或者聚氨酯里留下小孔~应该是属于物理发泡，不产生化学反应。截止目前，戊烷给eps发泡已经是一个成熟的体系，而环戊烷给聚氨酯发泡则还在发展，由于现在国家紧抓工业安全，能给聚氨酯把发泡剂从141b换成环戊烷的厂家寥寥无几，主要还是海尔海信这种大型冰箱厂。
