A customer in the chemical industry came to NEXA sharing a challenge that he was experiencing on a valve whose seal was in contact with solvents.
NEXA sealing solution
NEXA decided to proceed testing the seal currently used by the customer. The seal was a simple FKM elastomer.
Other unused seals provided by the customer were tested in operation and showed hardness changes in the range of -30% and a delta volume of +60% on average.
On the basis of these results, NEXA suggested to use an FFKM specifically developed for this application: NEXA XFluor® 8032.
Samples were tested and, upon satisfactory results, NEXA XFluor® 8032 compound was approved for use by the customer.
Findings
- Zero leakage
- Improved sealing performance and safety
- Increased life of the seal
