Two of the chemical process industry's most frequently visited online sealing materials selection guides - the Chemical Resistance Guide (CRG) and the Kalrez® Applications Guide (KAG) - have been upgraded with new test data and the latest products to help process engineers make informed decisions on elastomeric materials and O-ring design.

The CRG and KAG, provided as a free service by DuPont Performance Elastomers (DPE), are the subject of over 5,000 industry visits per month. Users click on Chemical Resistance Guide for registration and immediate access at www.dupontelastomers.com/crg. Users can request a downloadable copy of the KAG at www.dupontelastomers.com/kag/

• An ethylene acrylic elastomer (AEM) category added to the "General Chemical Resistance Guide" from the Los Angeles Rubber Group, plus data on Vamac® AEM.
• Over 150 new ratings and data entries in the Viton® fluoroelastomer section of the fluids resistance guide, including chemicals used in food contact, pharmaceutical, biofuels and chemical processing applications.
• Easy cross referencing of entries in the fuel applications section, plus dual listings for 'pure' biofuel blends and "wet" biofuel blends - with data showing which seals are not recommended for use with "wet" biofuels.

The CRG is available at www.dupontelastomers.com/crg .
