Detailed Introduction
Hoffman vacuum pumps demonstrate excellent performance in terms of pumping speed and backstreaming rate. Compared with mineral‑oil‑based diffusion pump oils, they exhibit outstanding oxidation stability, resist oxidation upon exposure to air, are resistant to magnetic fields and radiation, and possess flame‑retardant properties.
Performance Features
◎ The saturated vapor pressure is extremely low at room temperature, with an ultimate vacuum level reaching 1 × 10⁻⁸ kPa.
◎ Excellent thermal stability and high-temperature resistance; it is resistant to oxidation even under prolonged exposure to operating temperatures of 200°C and in the presence of metallic catalysis. ◎ It demonstrates superior performance in terms of pumping speed and backstreaming rate.
◎ It exhibits excellent oxidation stability compared to mineral-oil-based diffusion pump oils, resisting oxidation when exposed to atmospheric air.
◎ It is resistant to magnetic field and radiation exposure and exhibits flame retardancy.
Scope of Application
◎ HFM-KS diffusion pump silicone oil can be used as an ultra-high vacuum diffusion pump oil in industries such as electronics, metallurgy, and instrumentation.
◎ It can be used as a high-temperature heat transfer medium and as a working fluid in instruments.
◎ It can serve as the working fluid for ultra-high‑performance diffusion pumps in industries such as electronics, aerospace, and nuclear energy.
