expansion and excellent heat conduction. Due to its low friction
characteristics Merkel Unival can also withstand dry running up
to a certain limit. In addition, its pliable and dense composition
allows Merkel Unival to seal effectively with a minimum of gland
pressure.
The packing is approved for use in the food processing industries.
