HFV-KS Diffusion Pump Oil (Synthetic)

Detailed Product Description

Property

Very low saturation vapor pressure, vacuum degree will reached to 10^-8kPa, superior to mineral diffusion pump oil
Excellent thermal stability, endure high temperature, not easy to oxidize under 200 and while being catalyzed by metal
Perform great volume flow rate and back stream rate character
Much better anti-oxidation than mineral oil does, difficult to oxidize when encountering
atmosphere
Resist to radiat, anti-fire

Application

Can be used in electrical, metallurgy, instrument industry for ultra high vacuum degree
Applied for heat carrier and instrument as transfer fluid
Suitable for industries requiring for ultra high vacuum degree such as spaceflight, nuclear
