The development of advanced rubber products often involves creating cellular structures to impart specific properties such as lightness, flexibility, cushioning, and insulation. Chemical blowing agents are essential for this, and Azodicarbonamide (AC blowing agent or ADCA) is a workhorse in the rubber industry. NINGBO INNO PHARMCHEM CO.,LTD., a reputable manufacturer and supplier from China, provides high-quality Azodicarbonamide that is instrumental in producing a wide range of foamed rubber articles. For those seeking to buy foaming agents for rubber applications, understanding Azodicarbonamide's capabilities is key.

Azodicarbonamide (CAS 123-77-3) is a chemical compound known for its ability to decompose at controlled temperatures, releasing gases that expand rubber compounds during vulcanization or molding. This process results in sponge rubber, microcellular rubber, and other foamed elastomers used across various industries.

Benefits of Azodicarbonamide in Rubber Foaming

When you purchase Azodicarbonamide from NINGBO INNO PHARMCHEM CO.,LTD., you gain access to a blowing agent with numerous advantages for rubber processing:

  • Versatile Decomposition Profile: While pure Azodicarbonamide decomposes around 200-205°C, its effectiveness in rubber foaming is often enhanced by accelerators or activators, allowing for a broader processing window. This means it can be tailored for various rubber types and curing systems.
  • High Gas Yield for Lightweighting: A primary benefit is its high gas evolution, enabling the creation of significantly lighter rubber products. This is crucial for applications where weight reduction is a key performance indicator.
  • Fine Cell Structure Control: The particle size and purity of Azodicarbonamide, as provided by our manufacturing expertise, contribute to achieving fine and uniformly distributed cells within the rubber matrix. This uniformity is critical for maintaining the mechanical integrity and performance characteristics of the foamed rubber.
  • Good Compatibility with Elastomers: Azodicarbonamide disperses well in a variety of elastomers, including natural rubber (NR), styrene-butadiene rubber (SBR), nitrile-butadiene rubber (NBR), and ethylene-propylene-diene monomer (EPDM) rubber.
  • Odorless and Non-Staining: The decomposition products are generally odorless and non-staining, preserving the aesthetic qualities of the finished rubber goods.

Applications in Foamed Rubber Products

Our Azodicarbonamide is widely applied in the production of:

  • Sponge Rubber Seals and Gaskets: Used in automotive, construction, and appliance industries for sealing and vibration dampening, providing flexibility and resilience.
  • Insulation Materials: Foamed NBR/PVC blends or EPDM are used for thermal and acoustic insulation in pipes, hoses, and automotive components.
  • Shock Absorbers and Cushions: Its ability to create a good cellular structure makes it ideal for components requiring energy absorption and impact resistance.
  • Footwear Components: Beyond EVA, it can also be used in certain rubber-based shoe components for enhanced cushioning and lightweight properties.
