- Polymer Name:Bromobutyl Rubber (BIIR)
G&E Blended PMSB is made from brominated isobutylene paramethylstyrene feedstocks selected for mooney, bromine and paramethylstyrene content to achieve a uniformly-blended polymer. G&E Blended PMSB is excellent for cost reductions in applications such as innerliners, non-cured tapes, construction adhesives and caulks. G&E Blended PMSB can be used as a direct partial replacement of prime butyl and halogenated butyl rubber.
