P-GR Y VAC 2 PFPE Grease with Ultra-Low Outgassing and NLGI 2 Firm for Semiconductors

- Brand: PFPE KING®
- Model: P-GR Y VAC 2
- Packaging: 1KG
- Key Ingredients: Perfluoropolyether, polytetrafluoroethylene, and additives

- Type: High vacuum PFPE grease, semiconductor grade lubricant, PFPE KING specialty grease, NLGI 2 oxygen safe grease.

- P-GR Y VAC 2 is a higher-consistency variant in the GR Y VAC series, formulated specifically for high-vacuum, extreme-temperature, and chemically aggressive environments.

- Base Oil: Perfluoropolyether (PFPE)
- Thickener: Polytetrafluoroethylene (PTFE)
- Color: White/Homogeneous
- Temperature Range: -20℃ to 250℃
- NLGI Grade: Grade 2 (Standard, firmer consistency compared to the softer Grade 1 variant)
- Vapor Pressure: Extremely low vapor pressure/high vacuum stability (capable of operating down to ultra-high vacuum ranges like 10ˉ¹³ torr

- High-Vacuum Systems: Engineered to prevent outgassing and maintain integrity in deep vacuum chambers, pumps, and valves.
- Semiconductor & Electronics: Widely used in wafer processing equipment, cleanrooms, and manufacturing components exposed to reactive gases.
- Firm Consistency: The NLGI Grade 2 formulation provides better structural stability under higher mechanical loads and higher speeds than Grade 1.
- Inertness: Highly resistant to aggressive chemicals, strong acids, oxygen, and liquid oxygen environments, while remaining neutral toward most plastics and elastomers.
