Chloro butyl rubber CIIR is a copolymer rubber of chloro isobutylene and isoprene. It has many of the attributes of butyl rubber, including low gas and moisture permeability, good vibration damping, low glass transition temperature, excellent resistance to ageing and weathering. Compared to butyl rubber, the chlorinated sites are more reactive, providing faster cure with lower amount of curatives and better adhesion to unsaturated rubbers and metals.
