Exxon™ butyl rubber
Butyl rubber is a copolymer of isobutylene and a small amount of isoprene providing for a highly saturated backbone. The primary properties of butyl rubber are excellent air-barrier performance, good flex fatigue and vibration damping.
Properties
- Low permeability to air, gases and moisture
- Vibration damping
- Low glass transition temperature
- Low modulus elastomer
- Low compression set
- Resistance to aging and to weathering from atmospheric exposure
- Wide vulcanization versatility
- Fast cure rates
- Processing safety: no nitrosamines or nitrosamines precursors Benefits of high extensibility
- Broad range of durometer and tensile strength properties
- Low filler content for specific gravity, cost-effective compounding
