Role In Critical Chemical Process Sealing For Kalrez® And
to Problem Solving Products about purchasing a Kalrez®
Release from DuPont (formerly named DuPont Performance Elastomers when this article was written)
its line-up of Viton® fluoroelastomers (FKM) and Kalrez®
perfluoroelastomer (FFKM) parts, DuPont Performance Elastomers
(DPE) offered a sealing product for virtually every critical chemical
process at Achema '06. The company showcased FDA repeat-use food
contact compliant Viton® GF-600S and Viton® Extreme™
ETP-600S --- the latest specialty types of Viton® fluoroelastomers
for critical pharmaceutical, food and beverage process sealing,
and Viton® A-401C fluoroelastomers for best-in-class standard
FFKM, the ultimate level of elastomeric sealing, DPE presented
Kalrez® Spectrum™ 6375 and Kalrez® Spectrum™
7075 perfluoroelastomer parts for the most aggressive chemical
process environments, and demonstrated that Kalrez® parts
can be more affordable than many may think with industry data
showing possible savings of up to 98 per cent in total system
running costs compared with alternative sealing materials.
types of Viton®
to DPE, the new Viton® GF-600S and Viton® Extreme™
ETP-600S types provide superior steam resistance than silicone,
better caustic cleaning fluid resistance versus EPDM and bisphenol-cured
FKM, and low total organic carbon and metal extractables similar
to PTFE. Both products are made with Advanced Polymer Architecture
(APA), a proprietary development by the company that improves the
processing performance of specialty fluoroelastomers. Viton®
A-401C, described as a widely available industry standard in chemical
process sealing, offers excellent resistance to compression set,
and to aliphatic, aromatic hydrocarbons.
developments are available through the company’s "Genuine
Viton®" programme [of which Problem Solving Products,
Inc. is a certified distributor] which provides assurance of sealing
products that contain 100 percent virgin Viton® as the sole
Spectrum™ 6375 enables users to standardize around one instead
of two or three sealing compounds in inventory by providing outstanding
performance in acids, bases, amines and steam up to 275°C
service temperature. Kalrez® Spectrum™ 7075 provides
extended seal life, sealing force retention and thermal resistance
up to 327°C in the most aggressive chemical process environments.
DPE also demonstrated
how chemical process engineers can save up to 98 per cent in total
system running costs by switching to Kalrez® perfluoroelastomer
parts. The data is based on calculations of initial seal purchase
cost + costs of installation, monitoring, downtime and failure,
over the lifetime of equipment in customer processes.
