Inorganic silicone defoamers are highly favored in the defoaming industry due to their unique advantages. They act rapidly to break foam by quickly disrupting surface tension, causing bubbles to collapse and dissipate swiftly. They also provide long-lasting foam suppression, effectively preventing foam reformation over extended periods and ensuring stable, uninterrupted production processes. Chemically stable, they exhibit excellent resistance to acids, alkalis, and high temperatures, maintaining reliable performance even under harsh chemical conditions and elevated temperatures. Furthermore, they possess good dispersibility, enabling uniform distribution throughout the system for optimal effectiveness. Additionally, they are non-toxic, environmentally friendly, and do not compromise product quality. As a result, inorganic silicone defoamers are widely used across industries such as textiles, coatings, and wastewater treatment to effectively address foam-related challenges.
Product Introduction：
Silicone oil defoamers are a class of highly efficient antifoaming agents formulated primarily with polyorganosiloxanes (such as dimethyl silicone oil) as the active ingredient, combined with emulsifiers, dispersants, stabilizers, and other additives, and refined through specialized manufacturing processes. Their core components are linear or cyclic polymethylsiloxanes, which exhibit extremely low surface tension, excellent chemical inertness, and outstanding thermal stability.
Product Advantages：
Rapid and Efficient Defoaming: Quickly penetrates the foam lamella, destabilizes it, and achieves defoaming within seconds.
Long-lasting Foam Suppression: Effectively inhibits the formation of new foam, ensuring continuous and stable production processes.
Broad Applicability: Maintains stable performance in acidic, alkaline, and high-temperature environments (from -50°C to +200°C).
Chemical Inertness: Does not react with other components in the system and does not compromise product quality.
High Safety: Non-toxic, odorless, and non-corrosive. Food-grade products comply with standards such as FDA and GB, making them suitable for use in the food, pharmaceutical, and related industries.
Excellent Dispersibility: Especially water-based emulsion products disperse uniformly in aqueous systems.
Service Industries
Petroleum Industry: Drilling fluids, crude oil distillation, amine-based desulfurization (e.g., ethanolamine absorption of H₂S/CO₂), aromatic extraction, lubricant production, etc.
Chemical Industry: Foam control in processes such as polymerization, solvent extraction, hydrocracking, and distillation.
Water Treatment: Foam suppression in biochemical aeration tanks and industrial wastewater treatment.
Coatings and Inks: Prevents bubble formation during coating application, enhancing surface smoothness.
Textile Dyeing and Finishing: Used in wet processing steps such as dyeing and fabric finishing.
Food and Pharmaceutical Industries: Used as a safe antifoaming additive in processes such as fermentation, concentration, and extraction (requires food-grade silicone oils, e.g., Dow Corning DC1520, AFE-1520, etc.).
