Foam Formation

Foam refers to the formation of gas bubbles compressed within a liquid or solid medium. Foam formation depends on various factors such as surface tension, surface area and pressure of the medium in which the foam forms. In industrial applications, foam control is critical for uninterrupted production, efficiency, cost and product performance. Unwanted foam formation occurring during the production process disrupts the manufacturing process while negatively affecting the quality of the final product. Causes of foam formation include cellulose derivatives, mixing speed, resins, and post-production filling and application methods.

Foam breakers are chemical additives used to prevent foam formation in environments where foam is undesired and in industrial processes, or to eliminate foam in environments where foam formation has already occurred.

Foam breakers reduce the surface tension of a suspension or emulsion and prevent foam formation.

Chemipol

Founded in Spain in 1979, Chemipol is one of the world's leading manufacturers of additives and biocides. With high technology, effective solutions and expert technical support, Chemipol has extensive experience in the foam breaker field and has achieved major worldwide success in performance and price with its Densipol PA and WO series. Densipol WO 3025 is a high-quality foam breaker that can be added directly to water-based systems and can be used over a wide pH range with other agents and binders in the system. It provides long-lasting effect. It is a stable product. WO 3025 is hydrocarbon-based and a foam breaker containing oil-based hydrophobic compounds. It is mineral oil-based. This new generation foam breaker formulated as mineral oil-based rapidly and permanently removes formed foam while also preventing foam formation from the very beginning of the process. Densipol WO 3025, offering the most optimal solution in terms of price-quality, provides excellent stability and emulsification. Densipol WO 3025 provides high-efficiency foam control during production. It demonstrates excellent compatibility with the use of different types of binders such as styrene acrylic, acrylic, alkyd (water-based), styrene butadiene and polyvinyl acetate. It is generally recommended to use 2/3 at the beginning and 1/3 before the binder. Densipol WO series is a highly preferred successful foam breaker due to its rapid, effective and lasting foam breaking and foam prevention performance, high pH resistance and high heat stability, excellent chemical stability, compatibility with other chemicals and low cost.
