| Brand Name | Huifeng |
| Application | Industrial Lubricant |
Performance 1.Extremely low saturated vapor pressure at room temperatures and limited vacuum reaches 1.0*10-8kPa. 2. Excellent thermal stability and high temperature resistance so that it has the ability to keep oxidization stability under 200°c with metal catalyst. 3. Good performanceregarding apumping spdde and reflux rate. 4. Better oxidation stability than that of the mineral oil if expose to the air. 5. Radiation resistanceand lowinflammability. Application 1. Can be used asultrahigh vacuum diffusion pump oil in dldctrical,metallurgy and instrument industries. 2.Used ascarrierfluidfor heatcarrier or instrument. 3. Used as working fluid of diffusion pump with ultrahing requirements in the electronics , aeronautics and nuclear industry.
