For chemical procurement professionals and R&D scientists in the B2B sector, understanding the properties and applications of key chemical intermediates is vital for making informed purchasing decisions. Antioxidant 1330, a high-performance phenolic antioxidant, is one such critical material used extensively in polymer stabilization. As a leading manufacturer and supplier based in China, we aim to provide clarity on this essential additive, helping you navigate its benefits and sourcing requirements.

Antioxidant 1330, chemically identified as 1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene (CAS No. 1709-70-2), is a sterically hindered phenolic compound. Its primary function is to protect organic substrates, most notably polymers, from thermo-oxidative degradation. This degradation process, often accelerated by heat and oxygen during manufacturing or product use, can lead to discoloration, loss of mechanical strength, and reduced service life. Antioxidant 1330 works by scavenging free radicals, thereby interrupting the auto-oxidation chain reaction.

The product's physical form is typically a white to off-white crystalline powder. Key properties that make it attractive for procurement include its high melting point (around 248-250°C), ensuring stability at processing temperatures, and its low volatility, which means it remains within the material matrix rather than evaporating. Furthermore, it exhibits a high resistance to extraction by water and solvents, a critical advantage for products exposed to challenging environments. For procurement managers, these attributes translate to reliable performance and extended product durability.

Antioxidant 1330 finds widespread application in various polymers, including polyolefins (polyethylene, polypropylene, polybutene), engineering plastics (polyamides, polyesters), elastomers, PVC, and adhesives. Its effectiveness can be further enhanced when used in combination with secondary antioxidants like phosphites or thioethers, creating synergistic blends that offer superior protection. This versatility allows formulators to tailor additive packages to specific needs, optimizing both performance and cost. Understanding these application synergies is key for R&D teams.

When sourcing Antioxidant 1330, it is crucial to partner with a reputable manufacturer and supplier. We pride ourselves on our rigorous quality control processes, ensuring high purity (typically ≥98.0%) and consistent batch-to-batch quality. Our competitive pricing structure, coupled with reliable supply chain management from China, makes us an ideal partner for your chemical procurement needs. We encourage all professionals seeking high-performance antioxidants to reach out for a detailed quote and to discuss your specific application requirements.
