Polyacrylate Elastomers in Engine Gasket Applications

Temperatures in the engine compartments of modern automotive models has been increasing over recent years. This has placed a greater reliance on the ability of elastomer components to seal the engine.

In this paper the basic chemistry of polyacrylates elastomers is discussed as well as their market share in engine gasket applications. This study also compares a number of elastomers against the relevant parameters identified as needed for successful engine gasket sealing. These include heat and oil resistance, as well as compressive stress relaxation.
