For chemical manufacturers and distributors, the ability to offer high-quality, performance-driven additives is key to market success. Antioxidant 1076 (CAS: 2082-79-3) is a prime example of such an indispensable material, particularly crucial for the stabilization of polyolefins like polyethylene and polypropylene. Understanding its properties and how to source it effectively from reputable suppliers in China can provide a significant competitive advantage.

Antioxidant 1076 is a sterically hindered phenolic antioxidant that acts as a powerful protector against thermo-oxidative degradation. This means it effectively scavenges free radicals formed when polymers are exposed to heat and oxygen, preventing chain scission and cross-linking reactions that lead to material embrittlement, discoloration, and loss of mechanical properties. As a supplier, offering this product means providing a solution that directly addresses common degradation issues faced by polymer processors.

Key Properties for Your Portfolio:

When building a product portfolio or sourcing materials for resale, the specifications of Antioxidant 1076 are critical. Its key attributes include:

  • Chemical Identity: CAS No. 2082-79-3, Molecular Formula C35H62O3, Molecular Weight 530.87.
  • Appearance: Typically a white to off-white powder, making it easy to handle and incorporate into formulations.
  • Melting Point: 50-52 °C (lit.), indicating its solid state at room temperature and ease of storage.
  • Solubility: Soluble in various organic solvents like chloroform and ethyl acetate, but poorly soluble in water, which is advantageous for applications where water resistance is needed.
  • Stability: Stable under recommended storage conditions, contributing to a reliable shelf life.

The effectiveness of Antioxidant 1076 in polyolefins is well-documented. It helps maintain melt flow index, tensile strength, and elongation at break during high-temperature processing and long-term aging. This makes it a staple for manufacturers of films, pipes, automotive parts, and consumer goods made from polyolefins.

Sourcing Excellence from China:

For businesses looking to buy Antioxidant 1076, partnering with a Chinese manufacturer offers distinct advantages in terms of cost-effectiveness and scale. A reliable supplier will ensure consistent purity levels (often 98% or higher) and a stable supply chain, crucial for B2B operations. When evaluating potential suppliers, consider their R&D capabilities, production capacity, and quality assurance processes. Access to detailed technical data sheets and the ability to provide samples are also vital for validating product suitability.

Antioxidant 1076 is not just a single additive; it’s often part of a broader stabilization package. Its synergistic effect with secondary antioxidants, such as phosphites (like Antioxidant 168) and thioesters, is a significant advantage for formulators seeking enhanced protection. This combination strategy allows for superior performance against a wider range of degradation mechanisms. As a chemical distributor or manufacturer, offering these combined solutions can further enhance your market offering.

In summary, for any chemical supplier aiming to provide comprehensive solutions for the polymer industry, stocking and promoting Antioxidant 1076 is a strategic imperative. Its proven performance, broad applicability in polyolefins and other plastics, and the availability of reliable sources from China make it an attractive product for procurement and sales teams alike.
