Description

Difluoromethane is a versatile hydrofluorocarbon (HFC) refrigerant and chemical intermediate. Its primary value lies in its favorable thermodynamic properties and lower global warming potential compared to many traditional refrigerants, making it a key component in modern, environmentally-conscious cooling systems. This product is essential for manufacturers and service providers in the HVAC&R industry, as well as for chemical synthesis in the pharmaceutical and agrochemical sectors.

Application

• Primary Refrigerant: Widely used as R-32 in residential and commercial air conditioning systems, heat pumps, and chillers.
• Blend Component: A critical ingredient in next-generation refrigerant blends (e.g., R-410A, R-407 series) designed for improved efficiency and reduced environmental impact.
• Chemical Synthesis: Serves as a fluorinating agent and building block in the production of pharmaceuticals, agrochemicals, and advanced polymers.
• Fire Suppression: Used as a component in certain clean agent fire extinguishing systems where electrical equipment is present.
• Propellant: Employed in specialized aerosol applications requiring specific pressure and solubility characteristics.
• Laboratory Reagent: Utilized in research and development for organic synthesis and material science.

Quality Control

Our Difluoromethane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as purity, moisture content, and acidity. Our quality assurance protocols are designed to meet the exacting standards of the refrigeration and chemical processing industries, ensuring reliable performance and safety in your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, ignition points, and incompatible materials. As a compressed liquefied gas, cylinders must be stored upright and secured. Keep container valves closed when not in use. Storage temperature should not exceed 50°C (122°F).
