KS274 vacuum diffusion pump lubricating oil KS-274 silicone oil

KS274 vacuum diffusion pump lubricating oil KS-274 silicone oil
  • Item NO :

    KS274
  • Type :

    274 diffusion pump oil HFV-KS

KS diffusion pump oil  Performance:

The saturated vapor pressure is extremely low at room temperature, and the ultimate vacuum can reach 1×10-5kPa.

 Excellent thermal stability, often at 200 °C working temperature and metal catalysis is not easy to oxidize

  It shows good performance in terms of pumping rate and reflux rate.

  It has oxidation stability compared to mineral oil diffusion pump oil, and it is not easy to oxidize when in contact with the atmosphere.

  Radiation that is resistant to magnetic field radiation is flame retardant.

 

 

KS diffusion pump oil Use:

KS diffusion pump silicone oil can be used as vacuum diffusion pump oil in electronics, metallurgy, instrumentation and other industries.

 It can be used as a high-temperature heat carrier and as a transfer liquid in the instrument.

 It can be used as a working fluid for diffusion pumps required by electronics, aerospace, nuclear

industry and other industries.
