ExxonMobil releases FEA database for Santoprene grades

Akron, Ohio - ExxonMobil Chemical says it has introduced a new finite element analysis (FEA) database for Santoprene specialty products for semi-dynamic applications. Meanwhile, the database for static applications that has been available for over 15 years has been updated. Both sets of data are invaluable for modelling Santoprene thermoplastic elastomers (TPEs) as they can help predict the behaviour of non-linear elastomeric materials.

The new FEA database for semi-dynamic applications initially starts at 23°C. This data was obtained by cycles of loading-unloading in the three modes of deformation - tension, compression and shear - up to the attainment of steady-state conditions which are met after a minimum of three to five cycles of deformation. These are used by design engineers in the structural analysis of semi-dynamic applications, like most weatherseals. Test data for Santoprene rubber grade 101-80 is available on the website (see below).

Available to designers for many years, the FEA database for static application has been fully upgraded and is available on the website. Data from testing at 23°C of all standard Santoprene TPE grades from 35 Shore A to 50 Shore D have been made available in a three page document with information related to constraints in tension and compression. FEA material models are available to design engineers, as well as the strain range of fittings with graphs.
