High temperatures

High temperatures

Beyond 100°C, the speed of oxidation of a lubricant doubles whenever the temperature is increased by 10°C, which explains the need for selecting the proper lubricant.

Generally, we observe the following :

    1. Evaporation of the most volatile components,

    2. Coking of the heaviest components (transformation into char),

    3. A change in consistency and/or viscosity,

    4. Rapid oxidation.


The consequences are a rupture in the protective lubricating film, friction between the surfaces and accelerated wear of the mechanisms.

In a large number of high temperature applications, synthetic-based lubricants provide a solution with respect to such constraints. They above all enable the following :

  1. Greater resistance to high temperature,

  2. Increased safety (high flash point and drop point),

  3. Larger intervals with respect to lubrication,

  4. A preserved machine environment (less vapour),

  5. And they above all maintain the protective lubricating film.


These phenomena can particularly be found in the food (industrial bakery and pastry making), metallurgy, aluminium (foundry, extrusion), glass works (oven and forming), textile (dry frame) and automotive (cataphoresis oven) industries, etc.
