Description

1,1,1,2-Tetrafluoroethane is a hydrofluorocarbon (HFC) refrigerant and propellant with the CAS number 811-97-2. This compound is valued for its zero ozone depletion potential (ODP) and serves as a key replacement for older, environmentally harmful chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). It is essential for manufacturers and service providers in the refrigeration, air conditioning, and aerosol industries seeking efficient, compliant, and sustainable solutions.

Application

• Primary refrigerant in medium-temperature commercial and domestic refrigeration systems.
• Blowing agent for the production of polyurethane and other polymer foams.
• Propellant in medical, technical, and cosmetic aerosol products (e.g., asthma inhalers, dusters).
• Component in refrigerant blends (R-404A, R-407A/C/F, R-410A) for various HVAC&R applications.
• Heat transfer fluid in specialized cooling circuits and chillers.
• Fire suppression agent in some portable and fixed fire extinguishing systems.
• Solvent and carrier fluid in precision cleaning and deposition processes.

Quality Control

Our 1,1,1,2-Tetrafluoroethane is manufactured under stringent quality management systems. Every batch is analyzed to meet or exceed industry specifications such as AHRI 700 and ISO 916. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, acidity, and non-condensable gases is provided to ensure reliable performance and regulatory compliance for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile and gaseous nature under standard conditions, cylinders must be kept upright and secured. Store away from incompatible materials such as strong alkalis and reactive metals.
