Product Description

china factory supply wholesale price for Beijing sifang SK-3 diffusion pump oil for vacuum coating machine diffusion pump

Sifang Brand diffusion pump oil adopt paraffinic mineral oil fractions as raw material,after deep purification of its components,then excised molecular distillation fraction and degassed in a high-vacuum ,precise temperature control can effectively guarantee the cut fractions,ensure the diffusion pump can quickly vaporize and condense during working,resulting in high-speed jet stream, greatly improved the pumping speed and vacuum degree of the diffusion pump.

Sifang brand diffusion pump oil has a low ultimate pressure at work,high pumping speed and good oxidation resistance.Can be widely used in optics, electronics, vacuum metallurgy, vacuum coating and other aspects of the defense industry for metal diffusion pump and glass diffusion pump.
