Braskem America PIB 16

Braskem America PIB 16 is a non-toxic polymer obtained through the polymerization of an isobutene-rich stream with specific catalysts. It mainly consists of aliphatic mono-olefins, offering a clear and bright product free from sediments or suspended matter. PIB 16 holds NSF certification, making it suitable for use in lubricants and synthetic oils, including those for food-grade and pharmaceutical-grade applications. Additionally, it serves as a plasticizer for thermoplastic resins like PE, PP, PVC, and others.
