Description
To meet the demand for greater sealing
integrity while maintaining process purity,
DuPont has a family of high-performance
perfluoro elastomer sealing materials
uniquely suited for pharmaceutical and
medical manufacturing. Similar to PTFE in
cleanliness, heat and chemical resistance,
DuPont™ Kalrez® has the resilience
and compressive strength that are
characteristic of frequently used materials
such as ethylene propylene polymers
(EPDMs), fluoroelastomers (FKMs) and
silicone rubber.
With its combination of thermal/chemical
performance and rubber-like sealing
ability, Kalrez® offers the pharmaceutical
industry a new level of protection against
process contamination and seal failure.
Multi-purpose Kalrez® seals increase
process and equipment flexibility and
may make it possible to standardize
on a single seal material for all process
environments.
Kalrez® 6230 (black) and 6221 (white)
parts have been developed to meet the
unique sealing needs of today’s highspeed,
fully automated pharmaceutical
and biopharmaceutical manufacturing
processes. Kalrez® parts are manufactured
by DuPont to ensure excellent quality,
cleanliness and performance.
