产品特点

 LEYBONOL pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature
and must be able to resist thermal decomposition and oxidization. They permit high pumping speeds
over a wide range of pressures.

Surface tension of the pump fluids must be high to reduce "creep" of oil films. They are chemically inert,
exhibit a high flash point and the evaporation heat is low.
