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.

Application

DAIKIN’s DAI-EL fluoroelastomer products are used in a wide variety of industries and applications. In general, fluoroelastomers are selected due to their superior heat and chemical resistance when compared with other types of rubber. While each market requires different balances of those strengths, DAI-EL can offer grades that exceed most any requirementc

- Automotive: OEMs continue to increase fuel efficiency, reduce emissions, eliminate fluid leaks and improve the efficiency of their systems.
- Chemical plants: Aggressive chemicals, steam, acids, and bases require sealing materials with above average fluid resistance and long-term operability
- Oil & Gas: Drilling processes and other downhole fluids contain additives likely to degrade standard rubber.
- Medical & Food: O-rings, gaskets, shaft seals and flexible connectors for food processing equipment where heat or aggressive chemicals impact rubbers performance
- Consumer and wearable: Soft, flexible, non-reactive materials which don't degrade in contact with oils and perspiration are required
- Aerospace: high operating temperatures and high altitudes require superior heat resistance and low-temperature performance

DAI-EL Fluoroelastomers for harsh temperatures and fuel contact environments

To meet all these requirements, DAIKIN has developed DAI-EL, a wide range of fluoroelastomer solutions providing superior temperature resistance. It also combines the most effective stability to all sorts of chemicals and fluids such as oil, diesel, ethanol mix or body fluid. With low permeation rate, DAI-EL fluoroelastomer allows meeting stringent automotive regulations about gas emission by reducing leakage significantly.
DAI-EL grades can also provide optimal flow-ability and compression set.
DAI-EL fluoroelastomers also offer to consumer goods designers, new colorability options and innovative touch experience, while ensuring resistance to everyday life aggression.
