Chemical Structure
Features
- Highly resistant to heat (120~140C), ozone, weather, and oxidation, and extremely excellent in electrical properties
- Low resistance to oil, low resistance to heat during sulfur vulcanization
- Poor molding processability compared to NBR, poor finishing processability during peroxide vulcanization, compared to sulfur vulcanization
