Product Description

Organic Silicon Defoamer is mainly composed of silicone oil and organic silicon components. Silicone oil is a non-volatile oily liquid at room temperature, insoluble or with low solubility in water, animal and vegetable oils, and mineral oils. It can withstand both high and low temperatures. Chemical inertness, stable physical properties, and no biological activity.

Advantage:

(1) Widely applicable: Due to the special chemical structure of silicone oil, it is not soluble in water or substances containing polar groups, nor is it soluble in hydrocarbons or organic compounds containing hydrocarbon groups.

(2) Low surface tension: The surface capacity of silicone oil is generally 20-21 dynes/cm, which is lower than the surface tension of water (72 dynes/cm) and general foaming liquids, and has good defoaming effect.

(3) Good thermal stability: Taking commonly used dimethyl silicone oil as an example, it can withstand 150 ℃ for a long time and above 300 ℃ for a short time, and its Si-O bond does not decompose.

(4) Good chemical stability: Due to the stability of Si-O bonds, silicone oil has high chemical stability and is difficult to react with other substances.

(5) Physiological inertness: Silicone oil has been proven to be non-toxic to humans and animals, with a median lethal dose greater than 34 grams per kilogram. Therefore, organosilicon defoamers (when combined with suitable non-toxic emulsifiers) can be safely used in industries such as food, medical, pharmaceutical, and cosmetics.

(6) Strong defoaming power: silicone defoamer can not only effectively break the generated foam, but also significantly inhibit foam and prevent the formation of foam.
