In the realm of specialty chemicals, particularly for polymer additives, purity is not just a specification; it's a guarantee of performance and reliability. For manufacturers relying on Antioxidant 136 to protect their products from degradation, understanding the significance of purity and how to ensure it during the sourcing process is paramount. This article, brought to you by NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of functional material additives, delves into the critical aspects of quality assurance for Antioxidant 136.

The Critical Role of Purity in Antioxidant 136

Antioxidant 136, with its chemical structure designed for efficient radical scavenging, relies on its precise composition to deliver optimal protection. Even minor impurities can significantly impact its performance:

  • Reduced Efficacy: Impurities can interfere with the antioxidant’s ability to trap free radicals or its synergistic interactions with other additives, leading to less effective stabilization.
  • Processing Issues: Certain impurities might volatilize at processing temperatures, causing fumes, discoloration, or residues, affecting both the product's quality and workplace safety.
  • Inconsistent Results: Variations in purity from batch to batch can lead to unpredictable outcomes in your manufacturing processes and final products.
  • Regulatory Concerns: For applications in sensitive sectors like food packaging or medical devices, the presence of unlisted impurities can lead to regulatory non-compliance.

Therefore, when you buy Antioxidant 136, prioritizing purity is essential.

Specifications to Verify When Sourcing

As a procurement professional, you should always look for suppliers who clearly provide and adhere to stringent product specifications. For Antioxidant 136, key indicators of purity include:

  • Assay: This measures the concentration of the active compound. A high assay, typically ≥98%, signifies greater purity.
  • Melting Point: A narrow and well-defined melting range (e.g., 130.0-135.0°C) indicates a pure substance. Broad ranges often suggest the presence of impurities.
  • Transmittance: High light transmittance values (e.g., ≥97% at 425nm, ≥98% at 500nm) demonstrate the absence of colored impurities.
  • Volatiles and Ash Content: Low percentages for these parameters (e.g., ≤0.5% volatiles, ≤0.1% ash) further confirm purity.

Verifying these specifications with your potential supplier is a non-negotiable step in ensuring product quality.
