Braskem America PIB 10

Braskem America PIB 10 is a non-toxic polymer obtained through the polymerization of an isobutene-rich stream with specific catalysts. Comprising mainly of aliphatic mono-olefins, it is a clear and bright product, free from sediments or suspended matter. This versatile polymer holds NSF certification, making it suitable for various applications. It finds use in lubricants and synthetic oils formulation, including those for food grade and pharmaceutical grade. Additionally, PIB 10 serves as an emollient agent in cosmetics and acts as a plasticizer for thermoplastic resins like PE, PP, PVC, and others.
