Product Features

  • Stable chemical inertness: Does not corrode materials or react with them; exhibits no yellowing or decomposition product formation during prolonged use, demonstrating excellent material compatibility.

  • Insulating properties: Excellent dielectric constant, high insulation.

  • Low surface tension and low kinematic viscosity: Good wetting properties, strong dissolving power, improved heat transfer efficiency, enhanced permeability, reduced adhesion to solid surfaces, improved coating and spraying performance, increased cleaning efficiency.

  • Residue-free: Rapid drying after use, leaves no residue or whitening.

  • Thermal Conductivity: Superior thermal management properties.

  • Cost-Effective: High boiling point advantage minimises evaporation losses.

  • Safety & Environmental Compliance: Non-flammable, non-combustible with no explosion risk; non-toxic and odourless. No components listed as carcinogens by OSHA, IARC or NTP, with high permissible exposure limits (TWA).

  • Versatile Range: Wide boiling point spectrum offering multiple options to meet diverse requirements.


Industry Applications

  • Thermal conduction and cooling media for heat dissipation in computer servers, electronic components, power batteries, energy storage systems, and more.

  • Semiconductor manufacturing, chip fabrication, packaging and testing, laser etching.

  • Cleaning and maintenance of electronic, electrical, and power equipment without power interruption or operational downtime.

  • Providing insulation protection within high-voltage equipment.

  • Cooling and lubrication during milling and grinding processes.

  • Precision cleaning, dehydration, leak detection, and testing of electronic components.

  • Solvent diluents, lubricant diluents, and other specialty solvents.

  • Thermal shock testing fluid.
