Isobutylene

Description

1. Product Overview
   Isobutylene is a high-value, light olefin hydrocarbon (C4H8) widely used as a critical intermediate in petrochemical synthesis and high-performance material manufacturing. It serves as a foundational feedstock for producing polyisobutylene (PIB), butyl rubber, antioxidants, fuel additives, and specialty chemicals. Its exceptional reactivity and versatility make it indispensable in both downstream polymer production and refining processes. In global industrial supply chains, isobutylene plays a strategically important role in enabling advanced materials, energy efficiency solutions, and high-durability synthetic products.
