According to Nexam, the benefits gained from using Nexamite PBO include improved hydrolytic stability (in polyesters and polycarbonates), improved thermal stability, and control of branching and the degree of crosslinking. The company says that the additive also enables the upgrading of spent and recycled material, particularly PET, PBT and various polyamides; facilitates the compatibilization of polymer blends such as PET/polyamide, PBT/polyamide and polycarbonate/PBT; and allows for the use of low-viscosity polymers. The recycling of polyethylene/polyamide is another application area. Several formulations are available for different processing/application scenarios, Nexam reports.
