Antioxidant 168

Product Overview

Antioxidant 168 is a high-performance secondary antioxidant widely recognized in the polymer industry for its exceptional ability to protect materials during processing. Chemically known as Tris(2,4-di-tert-butylphenyl) phosphite, this compound serves as a critical additive for enhancing the longevity and physical properties of various plastics. Our manufacturing process ensures industrial-grade purity, making it an ideal choice for demanding applications where thermal stability and color retention are paramount.

As a leading supplier in the specialty chemicals sector, we provide Antioxidant 168 that meets rigorous international standards. This product is specifically engineered to function synergistically with primary antioxidants, offering comprehensive protection against oxidative degradation throughout the lifecycle of the polymer product.

Chemical Mechanism And Performance

The primary function of Antioxidant 168 is the decomposition of hydroperoxides formed during the autoxidation of polymers. By neutralizing these unstable intermediates, it prevents chain scission and cross-linking reactions that lead to material failure. This mechanism is crucial during high-temperature processing steps such as extrusion and molding, where thermal stress can rapidly degrade polymer chains.

• Excellent resistance to extraction by water ensures durability in humid environments.
• Low volatility prevents loss of additive during high-heat processing.
• Superior synergist effect when combined with primary antioxidants like Antioxidant 1010.
• Maintains clarity and color stability in finished plastic products.

Technical Specifications

Industrial Applications

Antioxidant 168 demonstrates excellent compatibility with a broad range of polyolefins and engineering plastics. It is extensively used in the stabilization of polypropylene (PP), polyethylene (PE), polystyrene (PS), and ABS resins. Additionally, it is suitable for use in PVC, PU, polyester, PBT, PET, and PMMA formulations. This versatility makes it a staple additive for manufacturers in the packaging, automotive, and consumer goods industries.

Whether used in fiber production, film blowing, or injection molding, this antioxidant ensures that the final product retains its mechanical strength and aesthetic appeal. It is particularly effective in applications requiring long-term thermal aging resistance.

Quality Assurance And Storage

Every batch of Antioxidant 168 undergoes strict quality control testing to verify compliance with factory standards. We provide comprehensive Certificates of Analysis (COA) with each shipment to guarantee consistency and purity. Our facility adheres to global manufacturing practices to ensure product safety and reliability.

For optimal preservation, keep containers tightly closed in a cool, dry place. Avoid exposure to direct sunlight and moisture to maintain the chemical integrity of the powder. Proper storage ensures that the product remains effective until its intended use in your formulation process.
