What is a Silicone Antifoam? A silicone antifoam is typically made of hydrophobized silica finely dispersed within silicone fluid. This compound is often stabilized in the form of a water-based emulsion. Silicone antifoams are effective at foam control because of their strength at low concentrations, their chemical inertness, and their ability to rapidly spread over […]
Foam is a common challenge in many industries, from chemical processing to food and beverage and more. Foam can hinder production processes, decrease product quality, and increase the risk of equipment damage. To address these issues, non-silicone defoamers are often used to eliminate or control foam. What is a Defoamer? Defoamers are a type of […]
Foam is produced when gas (e.g., air) is added and becomes stabilized within a liquid (often water) containing impurities and surface-active agents (surfactants). The molecules of surfactants form a film that traps gas bubbles, preventing them from dissipating as they would in a pure liquid. Whether the foam produced rises to the surface (macrofoam) or […]
Defoamers play a critical role in ensuring foam does not affect the quality of products and processes during industrial applications. They are available in many variations to suit different operations, including oil-based, surfactant-based, and water-based. Below, we focus on water-based defoamers, outlining what they are and what benefits they offer. What Are Water-Based Defoamers? As […]
Many types of foods and ingredients foam during the production process. If foaming is permitted, it can alter the product’s appearance, manufacturing time, quality or performance. Food-grade antifoams and defoamers are used to prevent, control, remove or mitigate foam to ensure high-quality, consistent production. Not only do these antifoams have to meet food safety regulations […]
Hydrophobic silicas are a unique class of materials with a wide variety of functional attributes and beneficial properties making it ideal for numerous applications ranging from adhesives, greases, and sealants to personal care and processing aid products. At Applied Material Solutions, we offer high-quality fumed and precipitated hydrophobic silicas to provide superior performance for your […]
Antifoams and defoamers are vital for the safe, efficient operation of processes in a multitude of industries. Finding an experienced foam control supplier can save a great deal of hassle, as they are able to provide expert solutions catered to the unique needs of your project. Here are a few of the key factors to […]
For most fluid systems, foam control is a challenge to overcome. Pure liquids do not foam. In an aqueous system, contaminants such as surfactants, proteins, small solid particulates will form a stable foam in water. Foam will significantly reduce system efficiency where foam or entrained air is undesirable. To prevent foam problems and keep the […]
For most fluid systems, foam control is an interesting challenge to overcome. Pure liquids do not foam or will not form a stable foam. In an aqueous system, contaminants such as surfactants, proteins, small solid particulates will form a stable foam in water. Foam will significantly reduce the efficiency of a given system where foam […]
The formation of foam in aqueous processes and products—such as flume water for the transport of vegetables—can hinder or halt many industrial processing operations.
