In this edition :

Elastomer Seal   Do you use the same elastomer seal whether it's in acid or water, 100°C or 200°C?
If you do, you may run into unexpected downtime and lost production. To assist specifiers in seal selection, DuPont Performance Elastomers presented a shortened webinar of its popular course on "Selecting the Best Elastomer". If you missed it, the webinar called "Elastomers 101: Improve Productivity Through Better Seal Selection" is available for downloading on our website. Registration is required.

Seal Performance Analysis   Do Your Parts Ever Look Like This?
Did you identify and really fix the problem so that it hasn't happened again.. and again.. and again? To assist users DuPont Performance Elastomers has developed a methodology for seal performance analysis. Russ Schnell reviewed this methodology in DPE's latest webinar: "Improve Equipment Uptime Through Elastomer Seal Failure Analysis." This webinar is now available for downloading. Registration is required.   Download Improve Equipment Uptime
