For businesses in the polymer industry, the selection of a high-quality Antioxidant 168 (CAS 31570-04-4) is paramount to ensuring the performance and longevity of their products. As a leading manufacturer and supplier of this essential chemical additive, we understand the critical role it plays in preventing oxidative degradation during polymer processing. This guide aims to assist procurement managers and R&D scientists in identifying a trustworthy supplier in China for Antioxidant 168, ensuring consistent quality and competitive pricing.

Antioxidant 168, also known chemically as Tris(2,4-di-tert-butylphenyl) phosphite, is a secondary antioxidant valued for its low toxicity, low volatility, and exceptional thermal stability. It acts synergistically with primary antioxidants, such as phenolic antioxidants, to offer robust protection against degradation during high-temperature manufacturing processes like extrusion and molding. This protective action helps maintain the polymer's molecular weight, color, and overall mechanical properties.

When sourcing Antioxidant 168, factors such as purity, consistency, and supply chain reliability are key. Reputable manufacturers in China adhere to stringent quality control measures, ensuring that the product meets international standards. For instance, a purity level of ≥99% is often a benchmark for effective performance in demanding applications. Furthermore, the ability of the supplier to provide detailed technical specifications, including melting point, volatile matter content, and light transmittance, is crucial for R&D scientists and formulators.

Procurement managers looking to buy Antioxidant 168 at a competitive price should engage directly with established manufacturers. Direct sourcing from a Chinese manufacturer often translates to cost savings, bypassing intermediaries and ensuring better control over the supply chain. When inquiring about pricing, it's advisable to specify the required quantity and any particular packaging needs, such as 25kg cartons with inner plastic bags.

The applications for Antioxidant 168 are vast, spanning polyolefins (PE, PP), engineering plastics (PC, PA, ABS), elastomers, adhesives, and coatings. Its excellent hydrolysis resistance makes it a preferred choice in applications exposed to moisture. By partnering with a reliable manufacturer, you can secure a consistent supply of this vital additive, which is indispensable for enhancing the processing stability and durability of a wide array of polymer-based products. Choosing the right supplier is not just about the price of Antioxidant 168, but about ensuring the quality and reliability that underpin your product's success.
