The effectiveness of modern polymers hinges significantly on the additives used to enhance their properties and processing characteristics. Among these, Antioxidant 168 (CAS 31570-04-4) stands out as a versatile and highly effective secondary antioxidant. As a leading manufacturer and supplier, we delve into the extensive applications of this critical chemical additive across various polymer matrices.

Antioxidant 168, chemically known as Tris(2,4-di-tert-butylphenyl) phosphite, is primarily utilized as a processing stabilizer. Its primary function is to protect polymers from degradation caused by heat and shear stress during manufacturing processes such as extrusion, injection molding, and film blowing. It effectively decomposes hydroperoxides, thus preventing discoloration, loss of mechanical strength, and changes in molecular weight. This makes it invaluable for products where aesthetic appeal and performance integrity are crucial.

In the realm of polyolefins, including polyethylene (PE) and polypropylene (PP), Antioxidant 168 is indispensable. It ensures excellent melt stability and color retention, which are critical for applications in packaging, automotive parts, and textiles. For engineering plastics like polycarbonates (PC), polyamides (PA), and ABS resins, it contributes to maintaining their high-performance characteristics, resisting thermal-oxidative breakdown even under demanding conditions.

Furthermore, Antioxidant 168 finds significant utility in elastomers and rubber compounds. It helps preserve the flexibility and durability of synthetic rubbers, improving their resistance to aging and degradation. Its application extends to adhesives and coatings, where it enhances thermal stability and prevents yellowing, ensuring the long-term effectiveness and appearance of these formulations. The compound's excellent hydrolysis resistance further broadens its applicability in diverse environmental conditions.
