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 :
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 :
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.
