Defoamers Market - Snapshot
Defoamers, or antifoaming agents, are chemical additives that reduce and hamper the formation of foam in industrial processes. Defoamers are generally insoluble in the foaming medium and possess surface active properties. They offer low viscosity and spread rapidly on the foamy surface. This is an essential characteristic of defoamers. They have affinity to air-liquid surfaces, where they threaten the foam lamellas. This results in rupture of air bubbles and breakdown of the surface foam.
There are various types of defoamers available in the market such as oil-based, water-based, and silicone-based. Oil-based defoamers possess an oil carrier. The oil may be mineral oil, vegetable oil, white oil, or any other oil that is insoluble in the foaming medium, except silicone oil. Generally, wax or hydrophobic silica are added to oil-based defoamers in order to boost performance. Water-based defoamers are different types of waxes and oils dispersed in water base. These waxes are long chain fatty alcohols, fatty acid soaps, or esters, while the oils are often white oils or vegetable oils. Silicone-based defoamers are polymers based on silicon backbones. These can be delivered as oil or water-based emulsions. Silicone-based defoamers consist of hydrophobic silica dispersed in silica oil. Powder defoamers are oil-based defoamers on a particulate carrier such as silica. These are added to powdered products such as cement, plasters, and detergents in order to control foam. EO/PO-based defoamers contain copolymers such as polyethylene glycol and polypropylene glycol. These copolymers offer favorable dispersing properties and are delivered as oils, water solutions, or water-based emulsifiers. Alkyl poly-acrylates are usually utilized as defoamers in non-aqueous systems, wherein release of air is more important than the breakdown of surface foam. Alkyl poly-acrylates are delivered in solvent carriers such as petroleum distillates.
Paper & pulp is an important application industry for defoamers. Defoamers used in the paper & pulp industry include water-based defoamers, oil-based defoamers, powder defoamers, silicone-based defoamers, and alkyl polyacrylates defoamers. These defoamers tackle both problems of surface foam and entrained or entrapped air.
Defoamers are widely utilized in the water treatment industry. Hydrocarbon-based defoamers are widely employed in sewage treatment applications. Silicone-based defoamers are generally not preferred due to their high cost. Polyethylene glycol monoalkyl ether defoamers are used for desalination of water. Silicone-based defoamers are also utilized in this application to some extent.
The problem of foaming in water-based paints is primarily found during the pigment stage of paint manufacture. The entrapped air within the pigment is displaced as wetting occurs and becomes entrapped in the mill base. It is also common in water-based printing inks and with solvent-based paints and inks. Silicone-based, silicone-free, oil-based, or wax-based defoamers can be used in paint and coating applications as per formulation requirements.
Usually, defoamers are extensively utilized in the sugar beet industry. They are used in fried foods such as potato chips and various other fried snacks. They are employed in the fast food industry for products such as fried chicken, chicken nuggets, and French fries. Silicone-based defoamers are used in most aerated drinks and in cooking oil for the prevention of foaming, while deep frying. Defoamers can be employed directly or incorporated in low-foaming cleansing agents.
Silicone and non-silicone-based defoamers such as polyethylene oxide and propylene oxide-based defoamers are used extensively in the pharmaceutical industry. Silicone-based defoamers are utilized in the petroleum processing industry as most foaming problems are involved with non-aqueous systems. Both silicone and non-silicone-based defoamers are used in the construction industry, and a number of powder-based defoamers have been especially developed to be included in concrete powder mix before wetting.
Major demand for defoamers is from water treatment and paints & coatings industries. Defoamers play an important role in industrial manufacturing and processing of liquid paints and coatings. They are effective in application of coatings with brushes, rollers, or more sophisticated application methods such as spray or curtain coating. Stringent environmental regulations have led to the replacement of solvent-based system to waterborne coating system. Increased amount of special surfactants are utilized in waterborne coatings. This has led to the need for highly efficient defoamers. Excessive foam formation is likely to result in inefficiency; long grinding time, storage instability of paints and coatings formulation, and other issues such as crater formation, loss of adhesion, gloss reduction, and loss of opacity. Silicone-based, silicone-free, oil-based, or wax-based defoamers can be used in paints and coatings applications as per the formulation requirements. Higher usage of defoamers in the paints & coatings industry is expected to augment the defoamers market during the forecast period considering the positive outlook for the industry.
The defoamers market is highly fragmented; the top five manufacturers accounted for nearly 20% share of the market in 2016. Major companies operating in the defoamers market are large chemical companies with dedicated manufacturing technologies along with experience and expertise to manufacture defoamers. Most of the production of defoamers is focused on Europe. Major manufacturers and suppliers of silicone defoamer are primarily located in the U.S., Germany, Belgium, the Netherlands, and the U.K. Manufacturers operating in the market are widening their distribution channels across developing economies in order to cater to the rising demand for defoamers in these countries.
Defoamers Market – Overview
Defoamers, or antifoaming agents, are chemical additives that reduce and hamper the formation of foam in industrial processes. Defoamers are generally insoluble in the foaming medium and possess surface active properties. They offer low viscosity and spread rapidly on the foamy surface. This is an essential characteristic of defoamers. Defoamers have an affinity toward air-liquid surfaces, where they threaten the foam lamellas. This results in the rupture of air bubbles and breakdown of the surface foam.
Defoamers play a crucial role in pulp and paper mills, as they help lower the problem of foam. Defoamers also hamper the formation of foam. They are surface active agents such as esters or amides of fatty acids and PE glycols. Various types of issues occur due to the build-up of foam in paper mills. These include difficulties in formation of paper, creation of deposits, development of bacteria, and drainage problems. Furthermore, the effectiveness of pump is also hampered. Defoamers improve drainage in kraft pulp stock and sulfite stock in pulp mills. Usage of defoamers leads to reduced paper breaking, thus improving paper machine operation effectiveness. Defoamers facilitate lower steam consumption. This helps save energy and costs. These properties are anticipated to drive the defoamers market.
Demand for defoamers is currently high in water treatment and food & beverages segments. However, the demand for defoamers in paints & coatings and metalworking fluids segments is expected to rise significantly during the forecast period.
