Material Notes:
Butyl rubber is a copolymer of isobutylene and a small percentage of isoprene.PropertiesWith 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
