Daikin’s DAI-EL fluoroelastomer and perfluoroelastomer products provide excellent high temperature and aggressive fluids resistance in sealing and fluid transport applications for automotive, oil and gas, aerospace, chemical process, small engine, and other harsh sealing environments. Daikin’s global technical and manufacturing resources support new developments and application of DAI-EL, each designed to meet specific OEM (end user) and fabricator (processor) requirements. In the Americas, as well as in Asia and Europe, Daikin partners with you to provide the best fluoroelastomer product solutions available in the world today.
DAI-EL: Selection Guide
Selecting a fluoroelastomer grade is often a difficult exercise in balancing performance requirements, processing considerations, and cost. To help you overcome this challenge, DAI-EL has created a selection guide with pertinent information and detailed recommendations. Whether you have a specific processing method and performance property in mind or are interested in exploring where different properties might take you, the DAI-EL selection guide is a powerful tool at your disposal. For additional information and product recommendations, please contact the DAI-EL technical service team.
DAI-EL: Fluid Resistance Guide
Fluoroelastomers and perfluoroelastomers offer superior acid, base, chemical, and fuel resistance compared to other types of rubber. However, significant performance differences exist within these product families. To assist you in determining which grades are most suitable for your operating environment, Daikin has created a chemical resistance guide. This guide details expected performance including volume swell data in harsh operating conditions. While comprehensive, this guide is not exhaustive so for additional information please contact the DAI-EL technical service team.
Effect of Fluorine Content
The fluorine content of a DAI-EL grade affects many things, especially low temperature properties and fluid resistance. In general, the lower the service temperature and volume swell of a compound, the better. However, as the chart below depicts, when selecting a fluoroelastomer there is generally a tradeoff between the two properties. For low temperature operating conditions, consider selecting a DAI-EL low temperature or copolymer grade. For sealing against aggressive fluids or other media, consider a 71% fluorine terpolymer or even a perfluoroelastomer.
