Product Introduction:
HDM-KSis silicone ultra-high vacuum diffusion pump oil with low saturated vapor pressure, and it is a colorless and transparent oily liquid.It has excellent thermal stability and high viscosity index, and can still maintain appropriate viscosity in a large temperature difference range.
Performance characteristics:
The saturated vapor pressure is extremely low at room temperature, and the ultimate vacuum degree can reach 1×10-8kpa.
Excellent thermal stability, high temperature resistance, not easy to be oxidized under the working temperature of 200℃ and metal catalysis.
It shows good performance in pumping rate and reflux rate.
It has unparalleled excellent oxidation stability of mineral diffusion pump oil and is not easy to oxidize when it comes into contact with the atmosphere.
It can resist the radiation of magnetic field radiation and has flame retardancy.
Application scope:
HDM-KS ultra-high vacuum diffusion pump silicone oil can be used as ultra-high vacuum diffusion pump oil in electronics, metallurgy, instrumentation and other industries.
It can be used as high-temperature heat carrier and transfer liquid in instruments.
Can be use as working fluid of ultra-high diffusion pump required by industries such as electronics, aerospace, nuclear industry and that like.
