Products Description
Highly Reactive Polyisobutylene (HR-PIB), CAS No. 9003-27-4, is a high-performance hydrocarbon polymer characterized by a high content of terminal vinylidene double bonds.
Compared with conventional PIB, HR-PIB offers significantly higher reactivity, making it the raw material for the production of polyisobutylene succinic anhydride (PIBSA) and lubricant additives.
Our Highly Reactive PIB is produced under controlled polymerization conditions to ensure stable molecular weight distribution and high vinylidene content.
