(57) [Summary] [Structure] 1. 2-trifluoromethyl-3,3,3- A foaming agent for producing a plastic foam made of trifluoro-1-propene. 2. 2-trifluoromethyl-3,3 as a foaming agent A method for producing a plastic foam, which comprises using 3-trifluoro-1-propene. [Effect] With the use of a foaming agent that has no danger of destroying the ozone layer, is nonflammable, and has excellent compatibility with the foam material, it has excellent heat insulation performance, mechanical strength, and dimensional stability. A plastic foam is obtained. |
