Foamed PVC has gained considerable traction across various industries due to its lightweight nature, excellent insulation properties, and structural integrity. Achieving these desirable characteristics in foamed PVC products relies heavily on the precise control of the foaming process, which is significantly influenced by the quality of processing aids used. NINGBO INNO PHARMCHEM CO.,LTD. provides ACR-401, an advanced acrylic processing aid that is instrumental in mastering the complexities of PVC foaming.

The Science Behind PVC Foaming: The creation of foamed PVC involves the introduction of blowing agents into the PVC matrix, which decompose at processing temperatures to release gases. These gases form bubbles within the molten polymer. For a successful foam structure—one that is uniform, has a low density, and high strength—these bubbles must be stabilized. This is where processing aids like ACR-401 come into play. They influence the rheological properties of the PVC melt, helping to stabilize the nascent bubbles and prevent their collapse or coalescence.

ACR-401: The Key to Low Density, High Strength Foams: ACR-401, as a high molecular weight acrylic copolymer, excels in stabilizing the microcells generated during the foaming process. By promoting a homogeneous melt and enhancing the viscoelasticity of the PVC compound, it ensures that the generated gas cells are evenly distributed and maintained. This leads directly to the production of foamed PVC products with the sought-after combination of low density and high impact strength. The effectiveness of ACR-401 in this regard aligns with the goal to achieve low density high strength PVC foam with processing aid.

Improving Surface Quality in Foamed PVC: Beyond the internal structure, the surface finish of foamed PVC products is also critical. ACR-401 contributes significantly to improving the surface quality, ensuring a smooth and aesthetically pleasing finish. This is vital for applications such as PVC foam boards for interior design, signage, and packaging. The processing aid's ability to promote even plasticization and melt flow helps to prevent surface imperfections.
