PEACE IN THE MODERN MANUFACTURING PROCESS
The current chemical and petrochemical industry works non-stop on improving its procedures, enhancing productivity and reducing costs. This results in an increase in productive times, less time for scheduled maintenance and the need to minimize unexpected plant shutdowns. Under these circumstances, the selection of sealing materials is an increasingly important priority regarding the reduction of risks of plant shutdown. To give an answer to this, Kalrez was developed.
An elastomer of excellent performance and reliability, which combines the characteristics of excellent rubber seals with chemical resistance to teflon, providing resistance to temperatures up to 327°C in continuous work and tolerating even higher temperature peaks.
KALREZ is a DuPont Performance Specialty Products’ registered trademark.
