China Silicone Defoamer Manufacturers, Suppliers, Factory
Silicone defoamer is a high-performance foam control agent widely used in industrial and household applications. Unlike traditional defoamers, silicone-based formulations consist of polydimethylsiloxane (PDMS) and hydrophobic silica, providing exceptional foam knockdown and long-lasting suppression. The working principle is simple: silicone defoamers have very low surface tension, allowing them to spread rapidly on foam film surfaces, creating localized tension gradients that rupture bubbles instantly.
Key advantages include chemical inertness, thermal stability (effective from 0°C to over 150°C), and excellent compatibility with both aqueous and non‑aqueous systems. At extremely low addition levels (typically 0.01–0.5%), silicone defoamers eliminate foam without affecting product clarity or performance. They are indispensable in laundry detergents, textile processing, pulp & paper manufacturing, water treatment, paints & coatings, and industrial cleaning. For laundry powder applications—like SQ-SF 102—silicone defoamers enable “low foam” formulations that save water, improve rinse efficiency, and protect washing machines. With growing demand for sustainable, concentrated detergents, silicone defoamers continue to be the preferred choice for reliable foam control.
