How does hydrolysis affects seals?
Literally, every fluid power system counts on soft-sealing technology to contain high-pressure liquid, allowing hydraulic energy to transmit useful work. The most common rubber technology in today’s fluid power system is synthetic, such as Buna nitrile or urethane. Each type of polymer has its advantages, but they also differ in their disadvantages. The hardness of […]

Freudenberg’s new method shows how static seals actually age
The seals used in plant engineering must have a very long service life. Once they are installed — to protect offshore wind turbine towers from salt corrosion, for example — customers (typically) require that they perform perfectly for more than 20 years. The service life of a seal is limited on the one hand by […]
