Application Advantages of Silicone Oil as an Antifoaming Agent

As an antifoaming agent, silicone oil is hailed as the "high-efficiency foam breaker" in industrial production. With its extremely low surface tension and excellent stability, silicone oil provides fast foam breakage and long-lasting foam suppression in foam-prone scenarios such as chemical reactions, food fermentation, and water treatment.

Fast Foam Breaking

Silicone oil microparticles rapidly disrupt the continuity and elasticity of the foam liquid membrane, causing the bubbles to break instantly. The foam-breaking speed is 3-5 times faster than traditional antifoaming agents, making it especially effective for sudden, large volumes of foam. In food fermentation, such as soy sauce and beer fermentation, a concentration of just 0.005% of highly concentrated silicone oil antifoam can break foam within 10 seconds and suppress it for over 4 hours, without affecting the product's flavor.

Stability

The core component of silicone oil antifoam is polydimethylsiloxane, which is chemically stable and resistant to reactions with other substances. It maintains its active properties in strong acidic or alkaline environments (pH 2-14) and at high temperatures (over 200°C). In high-temperature distillation reactions in the chemical industry, traditional antifoaming agents degrade and lose effectiveness, while high-temperature resistant silicone oil antifoams continue to work, ensuring smooth reactions. In water treatment, it can resist the corrosion of chemical agents in wastewater, providing long-lasting foam control and reducing water treatment costs.

Strong Compatibility

Modified silicone oil antifoams can be well integrated with a variety of systems, such as paints and adhesives, without causing separation or cloudiness. In paint production, silicone oil antifoams not only eliminate bubbles formed during production and application but also maintain the gloss and adhesion of the coating, improving overall coating quality. For example, the universal silicone oil antifoam used by Shandong PUNIO has been widely applied in industries such as papermaking and cleaning, with customers reporting not only high foam-breaking efficiency but also clear, stable systems.
