What is the Chemical Resistance Guide?

The Chemical Resistance Guide is a product selection tool to help you choose the best elastomer for your application. In the Introduction to Elastomers there is basic information about elastomers and the properties that are important when selecting them.  In the General Chemical Resistance Guide, DuPont worked with the Los Angeles Rubber Group (TLARGI) to update its valuable “Chemical Resistance Guide” which has been an industry resource with performance ratings of 20 elastomers in over 1000 chemicals, at room temperature.

What is the Kalrez® Application Guide?

The Kalrez® Application Guide is a product selection tool to assist in choosing the best Kalrez® product for your application. The selection tool rates all Kalrez® products in the various industries in which Kalrez® is used. Application temperatures and pressures can be input for more accurate product selection. The KAG can also assist in proper seal design for Kalrez® products in nine standard o-ring groove designs. Lastly, product datasheets are available for all the Kalrez® products.
