Antioxidant 168, chemically known as Tris(2,4-ditert-butylphenyl) phosphite, and identified by CAS No. 31570-04-4, stands as a cornerstone in polymer stabilization. Produced by NINGBO INNO PHARMCHEM CO.,LTD., this high-purity phosphite is celebrated for its exceptional performance as a secondary antioxidant and processing stabilizer. It typically appears as a fine white powder, ensuring ease of handling and incorporation into various material matrices. With an impressive assay often exceeding 99%, it meets stringent industry standards for purity and effectiveness.

The primary function of Antioxidant 168 revolves around its ability to effectively decompose hydroperoxides formed during the high-temperature processing of polymer materials. These hydroperoxides are key culprits in polymer degradation, leading to undesirable changes such as chain scission, crosslinking, and discoloration. By neutralizing these harmful intermediates, Antioxidant 168 plays a critical role in preserving the molecular integrity of polymers, thereby extending their service life and maintaining aesthetic appeal.

One of the most remarkable features of Antioxidant 168 is its hydrolytic stability and low volatility. These properties allow it to perform robustly even under demanding conditions, including exposure to moisture and elevated temperatures encountered during compounding, pelletizing, and fabrication. Its inherent thermal stability is crucial for thermoplastic polymers that require high processing temperatures. While potent on its own as a processing stabilizer, Antioxidant 168 demonstrates a significant synergistic effect when combined with primary hindered phenolic antioxidants, such as Antioxidant 1010 or 1076. This powerful combination provides comprehensive protection, guarding polymers against process-induced degradation and offering long-term thermo-oxidative stability during storage and end-use.

The versatility of Antioxidant 168 makes it indispensable across a broad spectrum of polymer materials and applications. It is widely employed in polyolefins, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and polypropylene (PP). Beyond polyolefins, its applications extend to polyamides (PA), polycarbonates (PC), ABS resins, polystyrene (PS) resins, polyvinyl chloride (PVC), and various engineering plastics. Furthermore, it finds use in elastomers such as BR, SEBS, and SBS, as well as in adhesives, sealants, coatings, paints, lubricants, oils, and synthetic tackifier resins. Its non-discoloring nature ensures that the visual quality of final products remains uncompromised.
