MG-Guard AO-725

MG-Guard™ AO-725 is an oligomeric high molecular weight primary antioxidant originally designed for the rubber industry. Due to the fact that this antioxidant is not held together with hydrolyzable functionalities, it is an excellent choice in thermoplastic applications requiring high additive extraction resistance or especially aggressive thermal use cases. Key applications include underwater submersion robustness (especially for UL wire jacketing testing), TPO roofing membranes, and under-the-hood. MG AO-725 is compatible in a number of thermoplastics, including: polyolefins (PE, PP), rubber-modified polyolefins (TPO, TPV), polyamides, EVA, PVC, polycarbonate, polyesters (PET, PBT), styrenics (ABS, PC/ABS, PS, SAN, ASA), and adhesives, among others. Due to the reactive phenolic structure, this material is prone to phenolic yellowing, and is best suited for applications.
