Apiezon T vacuum grease (EMS)

^-10Apiezon T medium temperature vacuum grease is a filled hydrocarbon grease for general sealing and lubrication in the medium temperature range. It is not suited for highly stressed bearings but excels in sticking power, is suitable for high to low vacua and is not silicone based. It is suitable for use between 10 and 120C. It features a tenacious consistency and thus extra cushioning between mated surfaces. It is superb for delicate glass joints for example. Apiezon T, like other greases in that family has a strong "gettering" action. It will absorb greasy or chemical contaminants from metal surfaces. The product has no contaminating effect on electrical equipment and is easily removed by hydrocarbon solvents. Apiezon T has found a niche as a reliable barrier to oxygen transmission in both vacuum and non-vacuum applications.

Features:

• Medium temperature range
• Sticking power
• Low to medium vacuum range
• Silicone free
• Easily removed
