Abstract: Disclosed is a process for preparing a thermoplastic polymer foam. The process includes providing a molten foamable composition including a thermoplastic polymer and a blowing agent. The blowing agent includes from about 2.0 to about 7.0 parts by weight per hundred resin of the thermoplastic polymer (phr) of 1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz) and from about 0.73 to about 15.37 phr of methyl formate. At least 50%, by weight, of the HFO-1336mzz is E-1,1,1,4,4,4-hexafluoro-2-butene (E-HFO-1336mzz). The thermoplastic polymer is a polystyrene homopolymer, a polystyrene copolymer, a styrene-acrylonitrile copolymer, a polyethylene, a polypropylene, or a blend thereof. The process also includes extruding the molten foamable composition to produce the thermoplastic polymer foam. The thermoplastic polymer foam has a plurality of cells with at least 80% of the cells being closed cells. The thermoplastic polymer foam is essentially free of structural defects. A thermoplastic polymer foam includes a thermoplastic polymer and a blowing agent.
