Rubber is still one of the most used materials for seals. The excellent elastic properties lend themselves perfectly to the sealing of an gap between two construction parts. If rubber is the right material for your seal, it must be determined which type of rubber can be of best use. This depends on the temperatures, loads, construction tolerances, life expectancy, influence of UV, Ozone or chemical environments. It is therefore very important to match the functional requirements of the application with the specific properties of the different types of rubbers.
