Defoamer

Defoamers are an initial part of paper and pulp production, which ensure the efficiency, safety and process quality. Controlling of foam formation is the key to prevent the negative consequences such as equipment damage, reduced product quality and health and safety risks. Regular updates and improvements to defoamer technology also play an important role in meeting environmental standards and optimizing production processes

Silicone- based defoamers

To solve the foaming problem we offer highly effective silicone defoamers, which are suitable for foam controlling in textile, pulp and paper, water treatment, metalworking and other industries.

Silicone-based defoamers provide high defoaming results, are very efficient and have a long lasting effect. Features of silicone defoamers:

– Economical to use, only 0.00001 to 1% of weight is required to achieve the desired result.

– Low surface tension, which allows to spread quickly over the foaming medium.

– Chemical inertness towards most substances. Their efficiency does not depend on the components which cause foaming.

– Wide temperature range, from -40°C to +250°C

– Low toxicity and others.

Silicone-based defoamers are well soluble in aromatic hydrocarbons and do not cause corrosion of metals. They have no unpleasant odour, do not cause allergic reactions and do not pose a threat to the environment. It is also important to note that silicone defoamers have appropriate sanitary and epidemiological certificates confirming their safety.

Polyester defoamer

Polyester defoamer is a non-silicone defoamer mainly composed of modified polyester. It has good dispersibility in water and strong dynamic anti-foaming ability.

It is mainly used in paper making, oil and gas, alumina, power plant desulphurisation, fermentation, water treatment, industrial cleaning and other industries

Polyhydric alcohol defoamer

Polyhydric alcohol defoamer is a silicone-free defoamer, prepared with high quality polyhydric alcohol as the main active ingredient, is mainly used to eliminate and control foaming in the wet part of paper machine, water treatment, and other industries and processes.

Main characteristics:

Effective defoamer. Our alcohol-based defoamers provide powerful and fast foam control. Due to high concentration of polyhydric alcohols, our product provides effective foam breakdown, preventing foam formation and spreading.
Liquid Form. Defoamers are made in liquid form, that makes them easy to use and integrate into the production process. Also it provides defoamer‘s equipartition and immediate effect on the foarmed foam.
Wide range of applications. Polyhydric alcohol defoamers are ideal for variety of industries including food processing, chemical manufacturing, oil and gas and many others.
Oleic acid and propylene glycol based defoamers. These components ensure high product stability and minimise environmental impact.
Economical use. Due to the high concentration of active ingredients, the defoamer provides a long-lasting effect, making it a cost-effective solution

Oil-based defoamers

Most mineral oil-based defoamers‘s efficiency is due to high coefficient of mineral oil osmosis and hydrophobic particles as an antifoaming active ingredient, which has additional synergistic defoaming effect.

It provides highly effective antifoaming and defoaming features in the pulp and paper industry, in paints and inks, and in other systems where a silicone-based defoamer cannot be used.

Powdered defoamers

Silicone-free and silicone-containing powdered defoamerare used for air degassing and foam control in aqueous systems such as food processing, dry cement slurry, oil drilling, water treatment and other processes.
