Apiezon H Grease 25g H11150001 1 bottle (25g)

A silicone-free high vacuum grease suitable for high temperature use in both scientific and industrial applications. It performs well over a wide temperature range of -10 to +240°C and maintains optimum consistency at temperatures between +10 to +110°C. It has excellent heat transfer properties, which transfers heat away from moving parts, reducing the risk of overheating and damage to heat-sensitive components. Exhibits good "stiction" or adhesion. Its powerful "gettering" action absorbs potentially harmful grease and chemical impurities from metal and glass surfaces. It is soluble in hydrocarbon solvents, making it easy to clean and remove. It has a vapor pressure of 1.7x10-9 Torr at 20°C. Applications: Lubrication of glass or metal plugs in vacuum systems, sealing of polymer joints in vacuum systems, leak detection, protection of metal contacts in vacuum encapsulated relays, sealing of polished glass/metal surfaces, optical surfaces in vacuum and laser systems (no fogging) Capacity: 25g tube *Not available for sale overseas
