Process for producing polymer foam using mixtures of pentafluoropropane and a hydrofluorocarbon having 3 to 6 carbon atoms

摘要：

The invention discloses novel azeotrope-like mixtures of fluorinated compounds which are useful for heating and cooling as heat transfer agents and/or refrigerants. The azeotrope-like mixture comprises: (a) pentafluoropropane; and (b) a hydrofluorocarbon of the formula: CxFyHz, wherein x is 3, 4, 5, or 6 and y and z are each independently 1 or a positive whole number such that the result of y/(y+z) is greater than 0.67.

摘要（中）：

本发明公开了可用作加热和冷却作为传热剂和/或制冷剂的氟化化合物的类似新颖的混合物。共沸混合物包含：（a）五氟丙烷; 和（b）下式的氢氟烃，其中x为3,4,5或6，y和z各自独立地为1或正整数，使得y /（y + z）的结果更大大于0.67。
