Azodicarbonamide (ADC) is a powerful and cost-effective chemical blowing agent widely used in the plastics and rubber industries. While its performance benefits are significant, proper handling and storage are crucial to ensure workplace safety, maintain product integrity, and prevent potential hazards. NINGBO INNO PHARMCHEM CO.,LTD., as a responsible manufacturer and supplier, emphasizes adherence to best practices for handling and storing ADC.

Understanding ADC's Properties for Safe Handling

ADC is an organic compound that decomposes under heat, releasing gases. This inherent property means it needs to be managed carefully to avoid premature decomposition or unintended reactions. Key considerations include its stability at room temperature and its sensitivity to heat and certain chemicals.

Storage Recommendations:

  • Cool, Dry Environment: Store ADC in a cool, dry place. Elevated temperatures can accelerate its decomposition rate. Avoid storing in direct sunlight or near heat sources such as steam pipes or furnaces.
  • Ventilation: Ensure the storage area is well-ventilated to prevent any accumulation of gases, should minor decomposition occur.
  • Segregation: Keep ADC away from incompatible materials. Direct contact with acids, alkalis, strong oxidizing agents, and reducing agents should be strictly prohibited as these can trigger exothermic reactions or decomposition.
  • Packaging Integrity: Always store ADC in its original, properly sealed packaging. Damaged packaging can lead to contamination or premature exposure to moisture and air, affecting its stability and performance.

Handling Precautions: Minimizing Exposure and Risk

When working with ADC, particularly during mixing, compounding, or processing, minimizing exposure to personnel and preventing cross-contamination are top priorities.

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles or a face shield, chemical-resistant gloves (e.g., nitrile or neoprene), and a dust mask or respirator, especially when handling powdered ADC. This protects against skin contact and inhalation of fine particles.
  • Ventilation: Ensure adequate local exhaust ventilation in areas where ADC is mixed or handled. This is crucial for capturing airborne dust and preventing inhalation.
  • Avoid Inhalation and Ingestion: Take care not to inhale the powder and avoid any direct skin contact or ingestion. Wash hands thoroughly after handling ADC, even if gloves were worn.
  • Controlled Environment: When adding ADC to polymer melts, ensure the processing temperature is controlled within the recommended range for the specific grade of ADC being used. Premature decomposition can lead to a loss of foaming efficiency and potentially create undesirable by-products.
  • Spill Management: In case of a spill, avoid generating dust. Gently sweep or vacuum the spilled material using an industrial vacuum cleaner equipped with a HEPA filter. Dispose of the spilled material according to local regulations. Do not use compressed air for cleaning.
