HFV-KS Diffusion Pump Oil (Synthetic)

Perform great volume flow rate and back stream rate character.Good quality and reasonable price,deliver the goods on time.
Performance
1. Extremely low saturated vapor pressure at room temperatures and limited vacuum reaches 1.0*10
-8
kPa.
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 performance regarding apumping spdde and reflux rate.
4. Better oxidation stability than that of the mineral oil if expose to the air.
5. Radiation resistance and low inflammability.

Application
1. Can be used asultrahigh vacuum diffusion pump oil in dldctrical,metallurgy and instrument industries.
2. Used as carrier fluid for heat carrier or instrument.
3. Used as working fluid of diffusion pump with ultrahing requirements in the electronics , aeronautics and nuclear industry.
