Name: HFV-KS Diffusion Pump Oil Model: HFV-KS Brief: Excellent thermal stability and high temperature resustance so that it has the ability to keep oxidization stability under 200 oC with metal catalyst.

详细介绍

Performance 

※ Extremely low saturated vapor pressure at room temperatures and limited vacuum

     reaches l x 10~5kpa.

※ Excellent thermal stability and high temperature resustance so that it has the ability 

   to keep oxidization stability under 200 oC with metal catalyst.

※ Good performance regarding pumping speed and reflux rate.

※ Better oxidation stability than that of the mineral oil if exposen to the air.

※ Radiation resistance and low inflammability.

Application         

※ Can be used as ultrahigh vacuum diffusion pump oil in electncal,metallurgical and instrument industries.

※ Used as carrier fluid for heat carrier or instrument.

※ Used as working fluid of diffusion pump with uitrahing requirements in the electronics. aeronautics and nuclear industry.
