Product Features??
- Stable chemical inertness: Does not corrode materials or react with them; does not yellow or form decomposition products during long-term use, ensuring excellent material compatibility.
- Insulating Properties: Excellent dielectric constant, high insulation.
- Low Surface Tension and Low Kinematic Viscosity: Superior wetting ability, strong solubility, enhanced heat transfer efficiency, improved permeability, reduced adhesion to solid surfaces, optimized coating and spraying performance, and increased cleaning efficiency.
- Residue-Free: Rapid drying after use, leaves no residue or whitening.
- Excellent thermal conductivity: Superior temperature control performance.
- Cost-saving: High boiling point advantage, low evaporation loss.
- Safe and environmentally friendly: No flash point or ignition point, no explosion or combustion risk; non-toxic and odorless. No components listed as carcinogens by OSHA, IARC, or NTP, with high permissible exposure limits (TWA).
- Multiple grades: Wide boiling point range, diverse options to meet various requirements.
