POLYISOBUTYLENE: A CRUCIAL BUILDING BLOCK FOR THE LUBRICANTS INDUSTRY

Polyisobutylene (PIB) is a versatile petrochemical. It plays important roles in lubricant manufacturing. In this article we take a look at the evolving PIB market.

Consolidated Supply Landscape of PIB Market What is PIB? PIB Is a liquid or semi-solid vinyl polymer formed by the cationic polymerization of isobutylene, but the raw materials may also include a mixture of isobutane and isobutylene, and fractions of C4 hydrocarbons along with isobutylene. PIBs can be of two types: high reactive (HR) PIBs and conventional PIBs. HR PIBs have a higher percentage of exo-terminal carbon-to-carbon double bonds (C=C), which makes them more reactive. In contrast, conventional PIBs have a lower percentage of exo-terminal C=C, which makes them relatively lesser reactive than HR PIBs. PIB is used as a precursor for the manufacture of lubricant additives as a lubricant basestock and as a thickener. On the basis of molecular weight, PIBs are sub-divided into several grades: es:

HIGH MID

>2,300 and <= 8,500

>=1,000 and <= 2,300

LOW <1,000 www.klinegroup.com
