Outgassing

High heat and temperature spikes can degrade elastomeric seals causing their crosslinking structure to become irreversibly damaged. In addition elastomeric seals can degrade under high temperatures causing outgassing to occur, thereby contaminating the process environment. The result is unscheduled downtime, or even worse, product loss. Figure 3 shows the outgassing properties of Kalrez® 7075UP versus Kalrez® 8475, Competitive FFKM D8 and a typical FKM product. Kalrez® 7075UP exhibited the lowest total outgassing rate.
