MORESCO Neovac MR-200 High-Vacuum Pump Oil (Made in Japan):
- Technical Specifications: Viscosity grade ISO VG 68 (Kinematic viscosity 68.0 mm²/s at 40°C, 8.8 mm²/s at 100°C), density 0.88 g/cm³ at 15°C, flash point (COC) >250°C, pour point <-12.5°C, ultimate saturated vapor pressure <1.3 x 10⁻⁴ Pa (at 20°C), highly refined fractional distilled mineral hydrocarbon fluid, Product of MORESCO Corporation (Matsumura Oil) Japan.
- Ultra-Low Saturated Vapor Pressure (<1.3 x 10⁻⁴ Pa): Enables rotary vacuum pumps to achieve and sustain deep ultimate high-vacuum levels without back-streaming.
- High Thermal & Oxidation Stability (Flash Point >250°C): Resists high operating temperatures, sludge formation, and acid varnish build-up under continuous industrial vacuum pumping.
- Excellent Water Demulsibility: Quickly separates moisture and condensable vapors, preventing pump cavitation and internal corrosion.
- Superior Lubricity & Wear Protection: Provides smooth hydrodynamic sealing for pump rotor vanes and cylinders.
- Applications: Semiconductor vacuum coating, vacuum freeze dryers, mass spectrometer backing pumps, transformer vacuum dehydration, and vacuum heat treatment ovens.
