Grease Features

Thermal greases are used to install and fasten sensors, while providing thermal contact and electrical insulation, with the sample. Apiezon N and Apiezon H greases are suitable for enhancing thermal contact, especially for sensors inserted into cavities. Apiezon N is for low temperature applications, while H is for high temperature.


Apiezon® Grease—types N and H

Apiezon® grease is well-suited for cryogenic use because of its low vapour pressure and high thermal conductivity. It is often used for non-permanent mounting and thermal anchoring of cryogenic temperature sensors as well as for lubricating joints and o-rings.

Apiezon® N: this general purpose grease enhances thermal contact and provides a temporary mounting method for temperature sensors. It is pliable at room temperatures and solidifies at cryogenic temperatures, which makes it easy to apply and remove the sensor (without damage) at room temperature. The grease is not an adhesive and will not necessarily hold a sensor or wires in place without some mechanical aid, such as a spring clip or tape. It is very good for sensors inserted into holes. Contains a high molecular weight polymeric hydrocarbon additive which gives it a tenacious, rubbery consistency allowing the grease to form a cushion between mating surfaces.

Apiezon® H: this grease will withstand temperatures up to 523 K (250 °C) without melting. It is designed for general purposes where operating temperatures necessitate the use of a relatively high melting point grease.

  • Stable
  • Non-permanent sensor mounting
  • Chemically inert
  • Non-toxic
  • Easily applied and removed
  • Excellent lubrication properties

Note: Can be removed using Xylene with isopropyl alcohol rinse.
