Description

Hydrochlorofluorocarbon-234 (HCFC-234) is a fluorinated hydrocarbon compound primarily used as a transitional refrigerant and foam-blowing agent. This product is valued for its specific thermodynamic properties and its role as a lower-ozone-depleting alternative to earlier CFCs. It is essential for industries involved in refrigeration system maintenance, thermal insulation manufacturing, and specialty chemical synthesis where precise volatile intermediates are required.

Application

• As a transitional refrigerant in specific industrial and commercial cooling systems.
• As a blowing agent in the production of polyurethane and polyisocyanurate foam insulation.
• As a solvent or cleaning agent in precision electronics and metal degreasing applications.
• As a chemical intermediate in the synthesis of other fluorinated compounds.
• As a propellant for specialized aerosol applications.
• Used in fire suppression systems as a component of certain gaseous mixtures.
• For laboratory research and development involving fluorocarbon chemistry.

Quality Control

Our HCFC-234 is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. All materials are subjected to rigorous analytical testing, including gas chromatography (GC) for purity and composition analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 15-25°C. Keep container tightly sealed when not in use to prevent loss and contamination.
