  1. New tables of the thermodynamic properties of HFC-134a have been developed and are presented here. These tables are based on experimental data from the database at the National Institute of Standards and Technology (NIST). Equations have been developed, based on the Modified Benedict-Webb-Rubin (MBWR) equation of state, which

  2. 134a can be used as a replacement for CFC-12 and HCFC-141b in thermoset foams. HFC-134a features properties that are advantageous for high value-in-use products and meets the requirements of safety/environmental issues. Freon™ 134a is nonflammable, has negligible photochemical reactivity, and low vapor thermal conductivity.
