1,1,1,2-Tetrafluoroethane
Formula: CH2FCF3, R-134a, HFC-134a
CAS No: 811-97-2
1,1,1,2-Tetrafluoroethane (R-134a) is a non-flammable haloalkane refrigerant valued for its stable thermodynamic performance and broad application range. EFC Gases & Advanced Materials supplies high-purity R-134a with rigorous analytical verification and controlled handling to ensure product integrity from production through delivery.
Applications include:
-
Cooling automotive, light-duty truck, and bus air conditioning systems
-
Refrigerating domestic units, commercial display cases, supermarket systems, and cold storage facilities
-
Chilling industrial process cooling, environmental chambers, and climate control systems
-
Transferring heat in specialty refrigeration, laboratory chillers, and thermal testing equipment
-
Propelling aerosol products in medical, pharmaceutical, and consumer applications
R-134a is recognized as an ozone-safe replacement for R-12, offering similar performance without contributing to ozone layer depletion. However, due to its moderate Global Warming Potential (GWP), it is subject to global regulatory phase-down programs such as the Kigali Amendment and regional F-Gas regulations. While lower-GWP alternatives are being introduced, R-134a remains widely used and accepted in many markets during this transition period.
EFC’s expertise in packaging, storage, and delivery ensures that R-134a meets the performance, safety, and compliance requirements of customers worldwide.
