Low foaming PVA refers to PVA solutions or formulations that incorporate defoaming agents (e.g., silicone-based, mineral oil, or polyether compounds) to suppress or eliminate foam during production or application. Foam can arise during mixing, processing, or high-speed operations, potentially compromising product quality or performance.

Foam Control: Defoamers disrupt foam stability, preventing air entrapment in PVA solutions. Improved Processing: Enhances uniformity in coatings, adhesives, or films by reducing foam-induced defects. Compatibility: Selected defoamers are tailored to PVA’s aqueous chemistry, ensuring stability without degrading polymer properties. Versatility: Effective in both high-temperature processing and ambient applications.
