Product Value
Sealing technology fulfills a variety of important functions for the smooth operation of machines and systems. Seals prevent leaks under the operating conditions prevailing in the application, ensuring the functional reliability of the system. The primary function of sealing technology is to prevent the unwanted escape of the sealed operating medium or the conveyed material from the interior of the machine or system component into the environment. The secondary function of sealing technology is to prevent the penetration of moisture, dirt, dust, and other contaminants present in the system environment into the interior of the machine or system components.
Material selection
Depending on the application, a wide range of materials and seal variants are available. Various factors such as pressure, speed, temperature, the type of medium, and other influencing factors influence the performance of these components, which are usually installed invisibly.
Typical materials are
- Acrylonitrile butadiene rubber (NBR)
- Polyurethane (PU)
- Fluorocarbon rubber (FKM or FPM)
- Polytetrafluoroethylene (PTFE)
