Material
PROGRESSION CA consists of a 0.20 mm thick aluminum sheet (AlMg alloy) that is coated on both sides with a 75 µm layer of nitrile rubber (NBR).
Properties
PROGRESSION CA exhibity the following specific properties, thanks to the AlMg core:

  • lightweight
  • in combination with aluminum components: the same coefficient of linear expansion
  • high thermal conductivity
  • non-corrosive

Gaskets made of PROGRESSION CA are usually beaded. Therefeore, these special nonferrous rubber-metal gaskets feature a unique combination of technical gasket properties:

  • very good ability to adapt to uneven sealing surfaces
  • very good sealing integrity against fluids and gases
  • recovery

Moreover, these gaskets offer very good resistance to oils, antifreeze, coolants (Freon), biodegradable lubricants, and nonpolar solvents.
Application
  • For sealed joints that are subject to moderate mechanical and/or thermal stresses, such as valve covers, oil pans and engine ancillaries, as well as for housings, compressors, pumps, and refrigerating modules.
  • Especially suitable for aluminum and magnesium components with low surface pressure.
Surfaces
The gasket material is coated on both sides with a non-stick layer. Therefore, additional surface treatment is unnecessary in most cases.

The data quoted above are valid for the material "as delivered" without any additional treatment. In view of the countless possible installation and operating conditions, definitive conclusions cannot be drawn for all applications regarding the behaviour in a sealed joint. Therefore, we do not give any warranty for technical data, as they do not represent assured characteristics. If you have any doubt, please contact us and specify the exact operating conditions.
