Apiezon Grease; Type H

Type H grease is designed for high temperatures (-10 to +240°C) in a wide range of applications in both science and industry. With good “friction”, grease H is ideal for use with laboratory glassware, but combined with properties of high thermal conductivity, it is the perfect choice for the electronics and space industries where heat sink media require adhesion.
Grease H is a filled hydrocarbon which exhibits excellent thermal conductivity, and strong absorption properties. The capability to absorb greasy or chemical impurities on metal and glass surfaces is a value “tool” required by electronic industries.

Description

Excellent lubricants
High purity, low vapor pressure – non-contamination in analysis
The working temperature range of each grease is dependent on the grade that is used
Easily applied, easily cleaned off
Silicone free. This benefits scientific users because the risk of sample contamination and consequently the risk of interference in analytical techniques such as infra-red or mass spctrometry, etc. is avoided
Approved by NASA and NATO
