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
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.
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
