In composition (c3), the supplemental lubricant(s) together are present in an amount of 5-50 wt.% ; and the flame suppressant is present in an amount of 0.5-30 wt.%, of the heat transfer composition. The heat transfer composition (c4) comprises the composition (c1) (at least 50 wt.%). The blowing agent comprises at least 5 wt.% of the azeotrope-like composition (c1). The sprayable composition is in the form of an aerosol. Preferred Components: In composition (c3), the adjuvant further includes at least one compatibilizer. The existing refrigerant is selected from HFC-134a, R-12, R-500, HFC-152a, and/or HFC-22. The refrigerant has a Global Warming Potential (GWP) of not greater than 1000. In the sprayable composition, the material to be sprayed is selected from cosmetics, cleaning solvent, lubricants and medicinal materials. Te medicinal material is a drug or a biologically active material.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: In composition (c3), the supplemental lubricant is selected from mineral oil, silicone oil, polyalkyl benzenes (PABs), polyol esters (POEs), polyalkylene glycols (PAGs), polyalkylene glycol esters (PAG esters), polyvinyl ethers (PVEs), and/or poly(alpha-olefins) (PAOs). The component capable of forming foam is selected from thermoplastic foams, polystyrene foams, polyethylene foams, low density polyethylene foams, extruded thermoplastic foams, polyurethane foams, and polyisocyanurate foams. The foamable composition further comprises at least one additive selected from dispersing agents, cell stabilizers, surfactants, and/or flame retardants. The existing refrigerant system comprises at least a first compressor having a first displacement and further comprising the step of removing the first compressor from the system and inserting in the system at least a second compressor having a larger displacement than the first compressor; where the existing refrigerant system is selected from automotive air conditioning systems, residential air conditioning systems, commercial air conditioning systems, residential refrigerator systems, residential freezer systems, commercial refrigerator systems, commercial freezer systems, chiller air conditioning systems, chiller refrigeration systems, and/or heat pump systems. The foam forming agent is polyurethane. In the one-component foam or foamable composition, at least a portion of the blowing agent is contained in the foam forming agent, or dissolved in the foam forming agent, or dissolved in the liquid foam forming agent and at least a second portion of the blowing agent is present as a separate gas phase. The one-component foam or foamable composition is contained in a pressurized container and where upon release from the pressurized container the dissolved blowing agent causes the expansion of the foam and the separate gas phase imparts propulsive force to the foam forming agent. EXAMPLE - An azeotrope-like composition composition comprising trans-1,3,3,3-pentafluoropropane (transHFO-1234ze) (24.30 wt.%) and propane (75.70 wt.%) was prepared.
