Fluoroelastomers

DAI-EL fluoroelastomer products provide excellent high temperature and aggressive fluids resistance for sealing and fluid transport applications in automotive, oil and gas, chemical processing, small engine, and other harsh sealing environments.

DESCRIPTION

Feartures of DAI-EL fluoroelastomer

DAI-EL fluoroelastomer products provide excellent high temperature and aggressive fluids resistance when compared with other elastomers,.

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 complex polymer design allows stable extrusion and molding processes for every type of technical rubber parts and fitting in a wide range of processing constraints, reducing the risk of failures and increasing productivity and covers the full range of copolymers and terpolymers for bisphenol and peroxide curing as well as specialty elastomers and ready to use compound.


Application

- 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.
- 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

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.
