XYC Fomblin Y LVAC 25/6 PFPE Vacuum Pump Oil Industrial Grade PFPE lubricant 1KG

Basic Information

XYC Fomblin Y LVAC 25/6 Industrial-Grade PFPE Vacuum Pump Oil
Product Type: Belongs to the perfluoropolyether (PFPE) vacuum pump oil category, one of the VPF series products.
Appearance: Typically a clear and transparent liquid.
Engineered for the most demanding industrial environments, the XYC Fomblin Y LVAC 25/6 is a premium perfluoropolyether (PFPE) vacuum pump oil designed for rotary vane and high-vacuum pumps exposed to harsh chemicals, aggressive oxidants, and extreme operating conditions.

Physicochemical Properties

- Average Molecular Weight: 3300 amu
- Kinematic Viscosity (20°C): 276 cSt (Higher viscosity for robust lubrication and oil film protection)
- Density (20°C): 1.90 g/cm³
- Pour Point: -35°C
- Vapor Pressure: 6 × 10⁻⁸ torr at 25°C; 6 × 10⁻⁵ torr at 100°C (Ensures superior vacuum performance with minimal gas release)
- Evaporation Loss (149°C, 22 hrs): 0.6 wt%

Product Attributes

- Total Chemical Inertness: Completely unreactive when exposed to strong acids, bases, and oxidizing agents such as chlorine, fluorine, boron trifluoride, oxygen, and ozone. Prevents carbonization and polymerization.
- Non-Flammable: Features no flash or fire point, ensuring maximum safety in high-oxygen or high-temperature environments.
- Exceptional Thermal Stability: Withstands continuous operation above 200°C, with a recommended operating threshold of up to 290°C in inert conditions.
- Clean System Performance: Resists deposit formation and coking even under ionizing radiation or ionic bombardment, keeping pump internals pristine.
- Broad Material Compatibility: Compatible with a wide range of metals, plastics, and common rubber elastomers.

Application Areas

- Semiconductor & Electronics: Essential for vacuum pumps handling corrosive gases in CVD, plasma etching, and ion implantation.
- Chemical & Pharmaceutical: Ideal for high-vacuum distillation systems utilizing strong acids or oxidants.
- Research & Nuclear Industry: Provides reliable lubrication for sensitive processes, including uranium hexafluoride (UF6) handling, mass spectrometry, and electron microscopy.

Usage & Maintenance Guidelines

- Corrosion Protection: For processes involving significant water vapor or moisture exposure, choose the Fomblin Y LVAC 25/6 RP (Rust Prevention) variant, which enhances anti-corrosive performance without compromising vacuum capability.
- Mandatory System Flushing: Fomblin PFPE oil is incompatible with mineral oils, synthetic hydrocarbons (PAO), and silicone oils. Before initial use, the pump must be thoroughly cleaned and dried using a specialized fluorinated solvent (e.g., Galden S90 or XZ 3-1). Failure to remove residual conventional oils will lead to emulsification and total loss of lubricating performance.
