Description

Apiezon Grease M is a high-vacuum, hydrocarbon-based lubricating grease designed for demanding industrial and scientific applications. Its core value lies in its exceptional chemical inertness, low vapor pressure, and wide operational temperature range, ensuring reliable performance in critical environments. This product is essential for industries requiring stable, non-reactive lubrication under extreme conditions, such as high-vacuum systems, analytical instrumentation, and specialized manufacturing processes. Apiezon Grease M CAS NO 12704-91-5 is a trusted material for maintaining the integrity and longevity of precision equipment.

Application

• High-vacuum system seals and lubricants for pumps, valves, and flanges.
• Lubrication for glassware joints and stopcocks in laboratory and chemical processing equipment.
• Sealant and lubricant for optical instruments, infrared cells, and spectrophotometer components.
• General-purpose lubricant for precision bearings and mechanisms operating in inert or controlled atmospheres.
• Thread sealant and anti-seize compound for assemblies in chemical processing plants.
• Lubrication for O-rings and gaskets in systems exposed to non-reactive gases or mild environments.
• Protective coating for metal surfaces to prevent corrosion during storage or transit.
