Polyvinyl Chloride (PVC) is a versatile polymer used in a vast array of products, from construction materials and automotive components to consumer goods. When PVC is processed into a foamed form, its properties can be significantly enhanced, offering benefits like reduced weight, improved insulation, and increased flexibility. The creation of these foamed structures relies heavily on chemical blowing agents, with Azodicarbonamide (AC blowing agent or ADCA) being a prominent and effective choice. NINGBO INNO PHARMCHEM CO.,LTD., a distinguished manufacturer and supplier from China, offers premium Azodicarbonamide crucial for achieving high-quality PVC foams.

Azodicarbonamide (CAS 123-77-3) is favored in PVC foaming due to its ability to decompose at temperatures compatible with PVC processing, releasing gases that create the cellular matrix. Its technical characteristics make it ideal for applications like artificial leather, flooring, insulation, and various molded PVC articles. Understanding its properties is key for any procurement manager or R&D scientist looking to optimize their PVC formulations.

The Technical Advantages of Azodicarbonamide for PVC

When you choose to buy Azodicarbonamide for your PVC manufacturing, you benefit from:

  • Optimal Decomposition Temperature: Azodicarbonamide decomposes efficiently within the typical processing range for PVC (around 180-210°C, depending on modifications and stabilizers), ensuring a controlled and effective foaming process. This predictable behavior is vital for consistent product quality.
  • High Gas Evolution: Generating a substantial volume of gas (≥220 ml/g) allows for the creation of lightweight PVC products with a good expansion ratio. This translates to material savings and enhanced product performance.
  • Fine and Uniform Cell Structure: Proper dispersion of Azodicarbonamide in PVC formulations leads to foams with fine, evenly distributed cells. This uniformity is critical for achieving desired physical properties such as flexibility, tensile strength, and impact resistance in PVC artificial leather and other products.
  • Self-Extinguishing Properties: The inherent self-extinguishing nature of Azodicarbonamide adds a valuable safety feature to the final PVC products, contributing to their fire-retardant capabilities.
  • Compatibility and Versatility: Azodicarbonamide is compatible with various PVC formulations, including both rigid and flexible PVC. It can be used in different processing methods such as extrusion, injection molding, and calendering.

Key PVC Applications Utilizing Azodicarbonamide

Our Azodicarbonamide is extensively used in:

  • PVC Artificial Leather: It imparts a soft, flexible, and aesthetically pleasing texture to artificial leather used in upholstery, automotive interiors, and fashion accessories.
  • PVC Flooring: Foamed PVC layers in flooring provide cushioning, sound insulation, and comfort underfoot.
  • PVC Profiles and Foams: Used in window profiles, decorative trims, and various extruded foam products requiring lightweight and insulation properties.
  • PVC Gaskets and Seals: Creates flexible and resilient foamed gaskets and seals for various industrial and consumer applications.
