Two of the most important product families in the UNICELL lineup are the D Series and the OH Series. While they share a commitment to consistent, high-quality foam structures, they are chemically distinct and serve different needs. Understanding when to use each one — and how they can even complement each other — gives formulators a significant advantage in optimizing both process efficiency and final product performance.The UNICELL D Series is one of the most widely used and effective families of chemical foaming agents in the plastics and rubber industries, known for its versatility, reliability, and high-performance characteristics. Based on azodicarbonamide (ADCA), the D Series is designed to generate gases during thermal decomposition, forming a controlled cellular structure within a wide range of materials such as PVC, polypropylene, polyethylene, EVA, ABS, polystyrene, and various synthetic rubbers. This broad compatibility allows manufacturers to use a single foaming system across multiple applications, making it an efficient and practical solution for diverse production needs.
Choosing the Right Chemical Foaming Agent: UNICELL D Series and OH Series
Foaming agents play a critical role in modern plastics and rubber manufacturing because they enable the production of lightweight, cost-efficient materials with tailored mechanical and physical properties. By generating gas within a polymer matrix during processing, foaming agents create cellular structures that reduce density while improving insulation, cushioning, and material performance. Choosing the right foaming agent is essential, as factors such as decomposition temperature, gas yield, compatibility with the base resin, cell uniformity, and processing stability all directly impact the quality and efficiency of the final product. Manufacturers must also consider how easily the foaming behavior can be controlled, whether through particle size or additives, to ensure consistent results across different processing methods.
