The selection of an appropriate foaming agent is a critical decision in the production of foamed plastics and rubber. While various options exist, Azodicarbonamide (AC) remains a popular and highly effective choice for many applications. NINGBO INNO PHARMCHEM CO.,LTD. provides valuable insights into why AC is often preferred and how manufacturers can make informed purchasing decisions.

Chemical blowing agents are broadly categorized based on their decomposition temperatures and gas evolution characteristics. AC stands out due to its high gas yield per unit mass and its relatively low cost-effectiveness compared to some other blowing agents. Its decomposition temperature range of approximately 200-205°C makes it suitable for a wide array of polymers processed at moderate to high temperatures, including PVC, PE, EVA, and ABS.

Compared to physical blowing agents (like HFCs or CO2), chemical blowing agents such as AC offer the advantage of generating gas internally within the polymer melt. This often leads to finer cell structures and more uniform foam density, which are desirable for many applications. Furthermore, AC is known for its self-extinguishing properties and its non-toxic, odorless decomposition residues, contributing to safer manufacturing processes and end products compared to some older chemical blowing agents.

While other chemical blowing agents exist, such as OBSH (4,4'-Oxybis(benzenesulfonyl hydrazide)) which decomposes at lower temperatures and produces less gas but offers finer cell structures and better dispersion in some systems, AC often provides a superior balance of cost, gas yield, and processing versatility for bulk applications. For instance, in the production of EVA footwear and mats, where significant foaming is required, AC is frequently the agent of choice.
