Description

Hfe-71 De is a highly volatile, non-flammable hydrofluoroether solvent engineered for precision cleaning and heat transfer applications. This compound matters for industries requiring a high-performance, environmentally preferable alternative to traditional solvents like HFCs and PFCs, offering excellent material compatibility and low toxicity. It is needed by manufacturers in the electronics, aerospace, and precision optics sectors for vapor degreasing, carrier fluid applications, and as a heat transfer fluid in temperature-controlled systems.

Application

• Precision Vapor Degreasing: For cleaning delicate electronic components, optical lenses, and medical devices without leaving residues.
• Carrier Fluid: Used in formulations for depositing lubricants, coatings, or other functional materials.
• Heat Transfer Fluid: Employed in closed-loop cooling systems for sensitive electronics and laboratory equipment due to its thermal stability.
• Solvent for Flux Removal: Effective in post-solder cleaning processes for printed circuit board assemblies (PCBAs).
• Drying Agent: Utilized in displacement drying of precision metal parts and components after aqueous cleaning.
• Reaction Solvent: Suitable for specialized chemical synthesis where an inert, non-polar medium is required.

Quality Control

Our Hfe-71 De is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm key parameters such as assay, non-volatile residue, acidity, and water content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee the material meets your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its high volatility, ensure containers are kept upright and sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
