Butyl rubber is a copolymer of isobutylene and a small percentage of isoprene.Properties- With careful compounding Butyl has really good tensile strength.
- Butyl has very low permeability to air and other gases.
- Excellent resistance to ozone, oxidation and sunlight.
- Butyl has very low resilience which makes it ideal for vibration damping and shock absorption applications.
- Butyl has moderate resistance to abrasion and compression set.
- Resistance to chemicals; resistance to most inorganic products. Highly resistant to mineral acids, alkalines and aqueous acids. Not recommended to use in contact with oils, or hydrocarbon solvents.All information provided by Trelleborg
