The Chemical Resistance Guide (CRG) and the Kalrez® Application Guide (KAG) are a service provided by DPE to help you choose the best elastomer to seal your specific process conditions.

December 2008

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 to help process engineers make the right decisions on elastomeric seals and O-ring design, plus over 150 new fluids resistance entries, including biofuels and FDA chemical ratings.

The CRG and KAG, provided as a free service by DuPont Performance Elastomers (DPE), are the subject of over 5000 industry visits per month. Users click on Chemical Resistance Guide at www.dupontelastomers.com/crg for the CRG, and can download the KAG directly at www.dupontelastomers.com/kag/.

Chemical Resistance Guide (CRG)

In addition to performance ratings of 20 elastomers in over 1 000 chemicals, the CRG now provides:

• An ethylene acrylic elastomer (AEM) category added to the “General Chemical Resistance Guide” from the Los Angles 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 FDA, biofuels and chemical processing applications.
• Easy cross referencing of entries in the fuel applications section, plus dual listings for 'pure' biofuel blends and biofuel blends with contaminants – with data showing which contaminants can have an adverse effect on seals.

The CRG is available at www.dupontelastomers.com by clicking on Chemical Resistance Guide.

Kalrez® Application Guide (KAG)

The KAG helps process and maintenance engineers select the best perfluoroelastomer seal by rating the resistance of Kalrez® compounds to virtually any combination of temperature and chemical media, and gives guidance on seal design. KAG updates and additions include:

• Information on Kalrez® 8900 perfluoroelastomer parts — the latest DPE product for semicon process sealing.
• Information on Kalrez® Spectrum™ 6380 and Kalrez® Spectrum™ 7090 products for the chemical process industry.
• Force Deflection information for Kalrez® 9100, Kalrez® 8002 and Kalrez® Spectrum™ 6380.
• Values for O-ring design calculations in English units are now given to four decimal places to reflect drawing dimensions more accurately.
• Users can now input a targeted initial O-ring stretch when designing a groove for a specific O-ring size.

The KAG can be downloaded from www.dupontelastomers.com/kag/.
