Description

Hydrochlorofluorocarbon-253 (HCFC-253) is a hydrochlorofluorocarbon compound primarily used as a refrigerant and foam-blowing agent. This product is valued for its specific thermodynamic properties and its role as a transitional substance in applications moving away from ozone-depleting CFCs. It is essential for manufacturers and service providers in the HVAC&R, industrial refrigeration, and foam insulation sectors requiring precise and reliable chemical intermediates.

Application

• Refrigerant Component: Used as a blend component in specialized refrigeration and air-conditioning systems.
• Foam Blowing Agent: Serves as an auxiliary blowing agent in the production of polyurethane and polyisocyanurate insulation foams.
• Chemical Intermediate: Acts as a precursor or intermediate in the synthesis of other fluorinated compounds.
• Fire Suppression Testing: Utilized in the development and calibration of fire extinguishing systems.
• Solvent Applications: Employed as a specialty solvent for cleaning and degreasing in precision electronics manufacturing.
• Laboratory Reagent: Used in research and development for studying fluorocarbon chemistry and properties.

Quality Control

Our HCFC-253 is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis including purity assay and impurity profiling via GC and GC-MS. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, keep container tightly sealed when not in use. Store separately from strong acids, bases, and oxidizing agents. Recommended storage temperature: 15-25°C.
