The creation of cellular or foamed plastics relies heavily on the precise performance of chemical blowing agents. Among the most widely adopted are AC foaming agents, which owe their effectiveness to specific physical and chemical properties. Two of the most crucial parameters that influence the success of a foaming process are the 'gas volume of foaming agent' and its 'particle size'. Understanding these metrics is key for manufacturers aiming to achieve specific product densities, mechanical properties, and surface finishes.

The 'gas volume of foaming agent' quantifies the amount of gas released per unit mass of the blowing agent upon decomposition. Typically measured in milliliters per gram (ml/g) under standard temperature and pressure (STP), a higher gas volume indicates greater efficiency in expanding the polymer matrix. For example, many AC foaming agents based on Azodicarbonamide (ADA) can achieve gas volumes ranging from 180 to over 220 ml/g. This efficiency directly translates into the ability to produce lighter-weight products, reduce material usage, and improve insulation properties. Manufacturers must select agents with appropriate gas volumes that match their desired product density and processing capabilities. NINGBO INNO PHARMCHEM CO.,LTD. offers agents with optimized gas volumes for various applications, ensuring efficient foaming for products like EVA injection slippers and PVC pipes.

Complementing gas volume is the 'particle size of chemical foaming agent'. Chemical blowing agents are typically supplied as fine powders. The particle size distribution significantly impacts how well the agent disperses within the polymer melt during processing. Finer particles, usually in the range of 8-10 microns or even smaller, lead to more uniform dispersion. This uniformity is critical because it ensures that gas is released evenly throughout the polymer, resulting in a homogeneous cellular structure with fine, closed cells. In contrast, larger or unevenly distributed particles can lead to cell coalescence, voids, or surface defects, compromising the product's mechanical strength and appearance. Choosing an AC foaming agent with a controlled and fine particle size, as offered by reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD., is essential for achieving predictable and high-quality foamed plastic parts.

By carefully considering both the 'gas volume of foaming agent' and the 'particle size of chemical foaming agent', manufacturers can fine-tune their foaming processes. Whether it's for enhancing cushioning in footwear or creating lightweight structural components, the technical specifications of the blowing agent are paramount.
