摘要
介绍了以Ecomate~®为代表的甲酸甲酯发泡剂的性质。与传统发泡剂相比,甲酸甲酯发泡剂具有绿色环保、燃点较高、与组分相容性好、所得泡沫密度和导热系数较低等优点。详细介绍了甲酸甲酯单独作为发泡剂,以及它与HCFC、HFC、戊烷类、HFO等形成的组合发泡剂在聚氨酯硬质泡沫生产中的应用情况。
The properties of methyl formate blowing agent presented as Ecomate are introduced.Comparing with the traditional blowing agent,the methyl formate blowing agent possesses the advantages of green eco-friendly,high burning point,good compatibility with other components,low density and thermal conductivity coefficient of the foam prepared with it and so on.The application situation of methyl formate alone used as blowing agent and the combined blowing agents made from it with HCFCs,HFCs,pentanes,HFOs and so on in production of polyurethane rigid foam is introduced in detail.
