Read moreWhich Materials Are Suitable for Heat-Resistant Flat Seals?
Heat-resistant flat seals are used in a wide range of industries, including chemicals, oil and gas, automotive and heavy industry. They are essential for ensuring the tightness, safety, efficiency and service life of systems operated under extreme thermal loads. But which materials are suitable for such applications? In this article, we look at the properties and possible uses of materials such as graphite, PTFE (polytetrafluoroethylene) and metal-reinforced seals. With this analysis, you can make the best choice of material for your specific requirements.
Read moreDifferences Between Graphite and EPDM Flat Seals
Flat seals play a central role in sealing technology, as they are used in a wide variety of industries and installation situations. Two of the most different materials for flat seals are graphite and EPDM (ethylene propylene diene rubber). Both materials have specific properties that predestine them for different applications. In this article, we look at the chemical, mechanical and thermal differences to help you make an informed decision.
Read moreWhy EPDM Flat Seals Are Suitable for Sanitary Applications
EPDM (ethylene propylene diene monomer) has established itself as an outstanding material for flat seals in sanitary applications. With its combination of chemical resistance, thermal stability and flexibility, it meets the high requirements of this industry. In this article, we examine the technical properties of EPDM and show why it is predestined for use in sanitary installations.
Read moreHow to Find the Right Flat Seal for Your Application
Choosing the right flat seal is crucial for tightness and therefore also for the safety, efficiency and service life of machines, plants and systems. Whether in the chemical industry, mechanical engineering or sanitary technology, the requirements placed on seals vary widely. In this guide, we show you how to find the optimum flat seal for your specific application.
Read moreWhich Standards Must Flat Seals Meet?
Flat seals play a crucial role in many industries, including chemicals, petrochemicals, mechanical engineering and sanitary technology. To ensure safety, durability and performance, these seals must comply with strict norms and standards. In this article, we look at the most important standards, their significance and technical details, so that flat seals meet the requirements of their applications.
