Medium molecular weight polyisobutylene’s average molecular weight
ranges between 40,000 and 120,000 g/mol. Medium molecular weight
polyisobutylene is employed as viscosity modifier, tack improver in
adhesive formulations, and primary binder in caulking and sealing
compounds. It is also used in fuel and lubricating oil additives. It is
extensively used as a protective barrier in the adhesive industry. For
instance, it is used where exposure to sunlight is a potential risk for
sealants. Medium molecular weight polyisobutylene is employed in
insulating glass sealants and roofing membranes in the construction
industry. Furthermore, it is used in protective films or acoustic barriers
in the automotive industry. Medium molecular weight polyisobutylene is
also an essential ingredient in the production of chewing gums.
