Global Top 14 Companies Accounted for 32% of total Polyisobutylene (PIB) market (QYResearch, 2021) | |
Polyisobutylene (PIB, also called polyisobutene, CAS 9003-27-4) is a vinyl polymer that is made from the monomer isobutylene (IB) by cationic polymerization. PIB is a colorless to light-yellow, elastic, semisolid or viscous substance. It is odorless, tasteless, and nontoxic. Because of their highly paraffinic and nonpolar nature, PIBs are soluble in aliphatic and aromatic hydrocarbon solvents and insoluble in polar solvents. Solubility generally decreases with increasing molecular weight of the polymer and increasing size of the aliphatic portion of the solvent molecule. The amorphous characteristics and low glass transition temperature (Tg = −62°C) of PIB impart high flexibility and permanent tack. Despite the favorable tack property, the adhesion of PIBs to many surfaces is weak because of their low polarity. This problem can be overcome by the addition of tackifiers (such as rosin ester resins) and other materials that will impart some polar properties to the formulation. The global key manufacturers of Polyisobutylene (PIB) include Daelim, Lubrizol, Infineum, TPC, BASF, Chevron Oronite, Ineos, Braskem, BASF-YPC, ENEOS, etc. In 2022, the global top five players had a share approximately 32.0% in terms of revenue.
