DuPont Performance Elastomers Provices A To Z Of Critical CPI Sealing With Viton® And Kalrez®

Total chemical process industry (CPI) sealing performance will be the keynote of DuPont Performance Elastomers ACHEMA 2006 line-up of Viton® fluoroelastomers (FKM) and Kalrez® perfluoroelastomer (FFKM) parts — combining the latest advances in chemical, temperature and pressure resistance in virtually all process media, with demonstrated cost savings over process equipment lifetime. The company will showcase FDA compliant types of Viton® GF-600S, Viton® Extreme™ ETP-600S, industry standard Viton® A-401C fluoroelastomers for critical process sealing, and Kalrez® Spectrum™ 6375 and 7075 for the most aggressive CPI environments.

"Mark of Genuine Viton®"

FDA compliant types of Viton® GF-600S and Viton® Extreme™ ETP-600S fluoroelastomers, made with Advanced Polymer Architecture, have been developed specially for critical pharmaceutical, food and beverage process sealing where repeat use and food contact compliance is required. Viton® A-401C is designed to set a new industry standard by offering excellent resistance to compression set and to aliphatic and aromatic hydrocarbons. These recent developments, as with all Viton® types, are available through the company's "Genuine Viton®" program which provides assurance that the sealing products are made of 100 percent Viton®.

Kalrez® affordability

For high-end FFKM sealing, DuPont Performance Elastomers will highlight Kalrez® Spectrum™ 6375 — enabling users to economise around one instead of two or three sealing compounds in inventory, and Kalrez® Spectrum™ 7075 — providing extended seal life, sealing force retention and thermal resistance up to 327°C in the most aggressive CPI environments. The company will also demonstrate the affordability of Kalrez® perfluoroelastomer seals via industry data showing how savings of up to 98 percent in total system running costs are possible by switching to Kalrez®.

Anti-corrosion seminar

DuPont Performance Elastomers will host an anti-corrosion seminar in partnership with DuPont at 13.30 on 17 May, 2006, in room Fantasie 2, Frankfurt Congress Centre. Norbert Bothe, applications consultant for Kalrez®, will update chemical process engineers on cost-effective seal selections for the most difficult chemical environments, including custom parts designed by state-of-the-art FEA methods to meet DIN 11864 specifications, in his paper "Kalrez® Perfluoroelastomer Parts – Sealing Solutions for Challenging Needs".
