Aerospace grade high vacuum grease

SEIVIO Vaculub J160 aerospace grade high vacuum grease is made of high-purity linear perfluoropolyether oil thickened with nanoscale ultra-fine PTFE. It is refined with special anti-corrosion additives and has very little volatilization under vacuum. Comply with aerospace standard ASTM‑E595 to avoid contamination of optical and electronic devices.

• Small evaporation loss under high vacuum, inhibiting molecular migration from contaminating optical devices;
• Pre-degassing treatment and high-temperature baking (such as 125°C/24 hours) accelerate the release of volatiles;
• Resistant to cosmic radiation, high-energy particles and ultraviolet rays, and the molecular chain is not easily broken and degraded;
• It does not freeze at low temperatures and has small starting torque, ensuring operating accuracy and sensitivity;
• Chemically inert, compatible with metals and some aerospace plastics/seals;
• No spontaneous ignition reaction when exposed to oxidants and propellants;
• It resists migration in microgravity and is not easy to flow or crawl to surrounding non-lubricated areas in a zero-gravity environment.

It is suitable for space applications, aerospace components, high-orbit satellites, solar panel deployment mechanisms, antenna pointing mechanisms, payloads and optical systems, space station docking and movable mechanism attitude controllers, etc. Widely used in bearings, guide rails and mechanism lubrication.
