Where metal meets metal - for example a plug connector meets a switch cabinet - there is usually a seal. In terms of temperature and media resistance, the seal must be as hard wearing as the other materials in the installation. One (almost) all-rounder is fluorocarbon rubber (FCM). It is resistant to weathering, ageing and ozone, as well as chemicals, and holds its own against the elements. If the ambient conditions are moderate, ethylene-propylene-diene rubber (EPDM) is also a good alternative. FCM has a small disadvantage - it is not suitable for very cold environments below -20 degrees. Silicone is more suitable for cold rooms or other freezing environments.
So how do you choose the best material for your application? Often there is no single answer that clearly indicates which material is best. But the right partner can offer knowledge and support through this process, helping you make the right choice.
