HFC-134a is internationally recognized as one of the main refrigerant working substances to substitute CFC-12. It does not contain the chlorine atom and gives no bad effects against ozonosphere and has an excellent safety performance. It is non-inflammable, non-explosive, non-toxic, non-pungent and non-corrosive. HCF-134a is a colorless gas under ordinary temperatures and a colorless & transparent liquid under the pressure of itself.


  • Used as a refrigerant to replace CFC -12 in mobile air conditioning & in residential, commercial and industrial refrigeration systems
  • Used as a blowing agent in rigid foam insulation
  • Used as an important component of blends such as R 404a, R 407c
  • Used as a propellant for extruded polystyrene foams (XPS)
