PVA Defoamer Selection Guide – Chemi Tech Solutions

Foam formation during polyvinyl alcohol (PVA) production and application often compromises process efficiency and product quality. Selecting a defoamer that eliminates foam rapidly while preserving dispersion stability is critical. Chemi Tech’s specialized defoamers for PVA systems achieve this balance through tailored molecular design, combining high foam-suppression efficiency with minimal interference to dispersion.  

The key advantage of Chemi Tech defoamers lies in their low surface tension and compatibility. Their formulation penetrates foam lamellae quickly, destabilizing bubbles without interacting with PVA molecules, thus maintaining homogeneous dispersion. Tests confirm that adding Chemi Tech defoamers causes no significant changes in PVA solution viscosity or flowability, proving zero adverse effects on dispersion.  

Moreover, these defoamers perform reliably under high-temperature and high-shear conditions, making them ideal for PVA coating, fiber spinning, or adhesive manufacturing. Users can select liquid or powder variants to match specific process requirements seamlessly.
