SKALN Diffusion pump oil 68 Product performance
Lower saturated vapor pressure, distillationrange narrow, highmolecular weight, pumping speed.
When the oil is heated to boiling statewill be supersonicjet and canquickly reach thevacuumpurpose.
Chemical composition is reasonable, with good oxidation stability and thermal stability.
150 oil return rate is lower, oil vapor can quickly condense into a new working fluidafter encountering cold wall.
SKALN Diffusion pump oil 68 Application scope
SKALN diffusion pump oil is mainly used for steam flow diffusion pump, and according to the requirements of the pressure to choose different molecular weight of ore-dispersedpump
Forvacuum distillation, vacuum smelting, vacuum coating, vacuum melting furnace and so on.
Can be used as electronics, aerospace, nuclear industry and other industries used diffusion pump working fluid
