Industries such as semiconductor manufacturing, vacuum metallurgy, and optoelectronics increasingly rely on high-vacuum environments. Vacuum diffusion pump oil, with its ultra-low vapor pressure and thermal stability, provides essential support to critical vacuum equipment.

Formulated from high-purity phenyl silicone oil, this pump oil is tailored for high-speed diffusion pumps. It maintains stable viscosity under thermal load, resists decomposition and coking, and minimizes equipment maintenance. Its low residue characteristics support ultra-high vacuum (UHV) operations without contamination.

Widely used in semiconductor lithography, electron beam welding, solar cell production, and scientific vacuum applications, vacuum pump oil enhances vacuum generation efficiency and long-term equipment reliability.

As vacuum technologies evolve toward higher precision, vacuum diffusion pump oil remains a cornerstone material in advanced equipment manufacturing.
