Braskem America PIB 6

Braskem America PIB 6 is a non-toxic polymer obtained through the polymerization of an isobutene-rich stream using specific catalysts. It mainly consists of aliphatic mono-olefins, resulting in a clear and bright product free from sediments or suspended matter. PIB 6 is NSF-certified and suitable for use in lubricants and synthetic oils, including those for food-grade and pharmaceutical-grade applications. Moreover, it serves as an emollient agent in cosmetics and functions as a plasticizer for thermoplastic resins like PE, PP, PVC, and others.
