Bellows in rubber expansion joints can be made of different materials, suitable for the medium flowing through. These can be, for example, CSM rubber (Hypalon) or FPM rubber (Viton). Both of them are resistant to a wide range of chemicals and different types of petroleum products. However, rubber expansion joints with additional, PTFE (Teflon) bellow [...]
Yes. Rubber expansion joints can operate in vacuum conditions. However, the value of vacuum depends on the type and diameter of the expansion joint. As the diameter increases, the value of a permissible operating vacuum in rubber expansion joints decreases. So, when the rubber expansion joints, especially those with larger diameters, are to withstand such [...]
EPDM rubber is normally used in expansion joints for hot water. It has great temperature resistance, even up to +130C (with peaks up to +150C) depending on the type of expansion joint. It shows considerable longevity undergoing only slow weathering. In addition, it is resistant to weak acid and base solutions, technical alcohols, esters and [...]
