In the realm of polymer processing, selecting the correct additives is paramount to achieving desired product outcomes. Foaming agents are critical for imparting properties like lightweighting, cushioning, and insulation. At NINGBO INNO PHARMCHEM CO., LTD., we offer a range of high-quality AC foaming agents, and this guide aims to help manufacturers choose the right one for their specific applications involving EVA, PE, PVC, and various rubber compounds.

The choice of an AC foaming agent is primarily dictated by the polymer being processed and the required decomposition temperature. Our AC foaming agent is based on azodicarbonamide (ADC), a versatile chemical blowing agent. For polymers like EVA (Ethylene-vinyl acetate) and PVC (Polyvinyl Chloride), which are typically processed at moderate temperatures, agents with decomposition temperatures around 125-135°C are ideal. Our specific AC foaming agent for EVA and PVC is formulated to decompose efficiently within this range, ensuring optimal foaming during hot-pressing molding and extrusion processes. This results in fine, uniform cell structures and enhanced physical properties such as tensile strength and elongation.

For Polyethylene (PE) processing, the selection might depend on the specific grade of PE and the intended application. Generally, AC foaming agents are effective in creating lightweight PE products for packaging, insulation, and automotive parts. The agent’s ability to deliver consistent gas evolution (measured in ml/g) and create a fine cellular structure is crucial for applications requiring good cushioning and insulation. Our AC blowing agent for PE provides these benefits, allowing for the creation of high-performance foamed PE materials.

When working with rubber compounds, including natural rubber, synthetic rubbers, and blends like PVC+NBR, the selection criteria for foaming agents also consider the vulcanization process. Our AC foaming agent is suitable for these applications, contributing to improved elasticity, cushioning, and durability. The agent's compatibility with various rubber systems ensures a stable foaming process, leading to products with enhanced mechanical properties and a desirable cellular structure.

Beyond polymer compatibility and decomposition temperature, other factors influence the choice of foaming agent. These include the required gas volume, particle size for dispersion, and the desired cell morphology (fine, uniform cells versus coarser cells). NINGBO INNO PHARMCHEM CO., LTD. offers AC foaming agents with controlled particle sizes and predictable gas evolution to meet diverse manufacturing needs. For those looking to buy AC foaming agent, consulting with our technical team can provide tailored recommendations to ensure optimal results, cost-effectiveness, and superior product quality. Our commitment to plastic foaming agent technology ensures we can support your innovation across all these applications.
