Loading hatches, separating columns, turbines or large separators, all have seal contact areas with large dimensions. Butt joint-vulcanized elastomer O-rings and elastomer profiles are a particularly economical solution for such applications. A special development means that a secure bond can be achieved between the seal ends of cut-to-size products by applying original elastomer material to the point of connection and vulcanizing the ends together in a tool. Butt joint-vulcanized large seals offers two decisive advantages: an inexpensive bonding procedure with low tool costs and improved dynamic load-bearing capacity when compared with bonded joints. Continuous profiles that have been glued are only suitable for use in static applications. Thanks to butt-joint vulcanization, these large seals can also withstand dynamic loads. Seals with large dimensions and diameters that are produced in this way also provide an economical seal for large shafts and slowly rotating components without the need for appropriate precision moldings, which are always associated with high tool costs at dimensions such as these. The elastomer materials used for this solution are carefully matched to the medium being sealed and the temperature limits in the application.
