Medium Molecular Weight Polyisobutylene
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.
