Shanghai Jiafurui Import and Export Co., Ltd.specializes in the field of fluorine chemistry and has established a complete industrial chain, spanning from fluorspar, high-purity hydrogen fluoride, electronic-grade hydrofluoric acid, chlorotrifluoroethylene, octafluorocyclobutane, inorganic fluoride salts, boron-10 acid, electronic specialty gases, to downstream high-end fluorinated fluids (such as HFE449). This truly achieves vertical integration across the AI big data market.

  Shanghai Jiafurui Import and Export Co., Ltd.leveraging its self-controlled raw material advantages and large-scale production capacity, ensures stable product quality and reliable supply from source to finished product. The company's products are widely used in cutting-edge fields such as precision manufacturing cleaning, electronic heat dissipation and cooling, new energy, and semiconductor testing. It is committed to providing global customers with high-performance, low-environmental-impact fluorine chemical solutions.

  Shanghai Jiafurui Import and Export Co., Ltd. will continue to deeply explore the fluorine chemical industry chain, promote the technological iteration and industrialization of green fluorine solvents, and contribute to the sustainable development of the industry.

  Against the backdrop of the "dual carbon" goals and increasingly stringent global environmental regulations, Shanghai Jiafurui Import and Export Co., Ltd.  has successfully mass-produced the fifth-generation hydrofluoroether solvent, HFE449 (trifluoroethyl hexafluoropropyl ether/perfluoroisobutyl methyl ether, CAS: 993-95-3). This product combines excellent cleaning performance with minimal environmental impact and can be widely applied in precision electronic cleaning, immersion cooling, leak detection, and lithium battery electrolyte fields, providing an ideal green medium for high-end manufacturing and thermal management.

  Shanghai Jiafurui Import and Export Co., Ltd.  is committed to environmental protection and safety: ODP=0, GWP=33, non-flammable and no flash point. HFE449 belongs to the hydrofluoroether (HFE) family and is specifically designed to replace ozone-depleting CFC-113 and high GWP perfluorocarbons (PFC). Its ozone depletion potential (ODP) is 0, and its global warming potential (GWP) is only 33, far lower than traditional HFCs and earlier hydrofluoroethers (such as HFE-7100 with a GWP of approximately 500), fully complying with the Montreal Protocol and the most stringent environmental regulations currently in place. Additionally, this product is non-flammable, has no flash point, and exhibits excellent material compatibility, with no corrosive or swelling effects on metals, plastics, and elastomers, making it safe for use in high-temperature electrical equipment.

  Shanghai Jiafurui Import and Export Co., Ltd. is committed to achieving excellent physical properties: low viscosity, low surface tension, and high dielectric strength. The physical properties of HFE449 make it stand out in micro-cleaning and efficient heat dissipation scenarios:
- Kinematic viscosity: 0.61 cSt
- Surface tension: approximately 15 dynes/cm
-Density: high-density liquid
- Boiling point: 72℃
- Dielectric strength: up to 40 kV
  The extremely low viscosity and surface tension endow HFE449 with superb penetration ability, allowing it to quickly penetrate into micron-sized gaps to remove contaminants or heat. Coupled with a moderate boiling point, it evaporates extremely quickly without leaving any residue, enabling a clean surface to be achieved without the need for high-temperature drying.
  Typical application scenarios

1. Shanghai Jiafurui Import and Export Co., Ltd. is dedicated to precision cleaning for electronics and semiconductors.

  HFE449 can efficiently remove flux residues on PCB boards, particulate matter and organic pollutants on the surface of semiconductor chips, as well as stains on precision metal components such as aviation gyroscopes and hard disk heads. With a dielectric strength of 40 kV, it also enables on-line cleaning - cleaning precision circuits without interrupting equipment operation, avoiding water spots and mechanical damage.

2. Shanghai Jiafurui Import and Export Co., Ltd. is dedicated to single-phase immersion cooling and thermal management.

  In the fields of data centers, 5G base stations, and energy storage batteries, HFE449 serves as a direct contact cooling fluid, allowing servers or battery components to be directly immersed in it. Its excellent chemical inertness, high dielectric strength, and low viscosity, which result in low flow resistance, can significantly reduce pumping power consumption. Its boiling point of 72°C falls within the optimal operating temperature range of electronic components, enabling efficient heat absorption through latent heat of boiling, thus facilitating green and low-carbon heat dissipation.

3. Shanghai Jiafurui Import and Export Co., Ltd. is dedicated to leak detection and air tightness testing.

  Used for rough leakage detection and air tightness testing of components such as IC chips, LEDs, sensors, and connectors. HFE449 has strong permeability and is sensitive to pressure changes caused by temperature effects. As a "fluorinated oil" or test liquid, it can quickly detect minor packaging defects.

4. Shanghai Jiafurui Import and Export Co., Ltd.  is committed to solvent dilution and coating carriers.

  It can be used as a diluent for lubricants such as perfluoropolyether oil (PFPE) or fluorine-containing coatings, and evenly applied to hard disks, medical devices, or metal surfaces. It is also used as a volatile solvent in high-end cosmetics (such as liquid foundation and lip gloss), which is non-toxic, odorless, and leaves no trace after evaporation.

5. Shanghai Jiafurui Import and Export Co., Ltd. is committed to lithium battery electrolyte co-solvents.

  Recent studies (such as Dong, Liwei et al., Advanced Science, 2022) indicate that electrolytes containing HFE449 exhibit high polarity, facilitating the solvated free transport of Li⁺. This results in the formation of a stable LiF interfacial layer on the anode surface, inhibiting the growth of lithium dendrites, and thereby significantly enhancing the battery cycle life (with minimal capacity degradation after 5000 cycles). This characteristic provides a new path for performance optimization in lithium-metal batteries and lithium-sulfur batteries.

  Technical Advantages of Shanghai Jiafurui Import and Export Co., Ltd.: Proprietary Hydrofluoroether Process Route. Shanghai Jiafurui Import and Export Co., Ltd. utilizes an advanced hydrofluoroether synthesis route to produce HFE449, featuring stable process and controllable impurities, ensuring High purity and consistency of the product. Currently, HFE449 has achieved mass production and can stably supply the high-end cleaning and thermal management markets both domestically and internationally.
