The High molecular weight polyisobutylene (HMPIB) is a specialized polymer known for its high viscosity, tackiness, and durability. Produced from isobutylene monomers through cationic polymerization, HMPIB is widely used in adhesives, sealants, lubricants, and protective coatings.

The global HMPIB market is expanding due to rising demand in automotive, construction, and industrial applications. In adhesives and sealants, it enhances tack and flexibility, while in lubricants it provides superior thickening and film-forming properties. The construction industry relies on HMPIB-based sealants for waterproofing, roofing membranes, synthetic rubber additive, high performance elastomer, polyisobutylene polymer, fuel and lubricant additive, adhesive and sealant ingredient and glazing applications.

Asia-Pacific dominates the market with robust automotive and construction sectors, while North America and Europe are witnessing strong growth from specialty applications. As industries prioritize performance and longevity, HMPIB remains a critical raw material for high-end formulations.
