What is a non-silicone defoamer?
Non-silicone defoamer, formulated with aldehydes and oleic acid complexes. Off-white with a yellow tinge; non-ionic. Suitable for PCB circuit boards (during development, ink removal, and wastewater stages). Also applicable to aluminum processing, as well as emulsion breaking and foam suppression in various wastewater treatment and industrial water systems, and for demulsification in cooling‑circulation water systems and other water‑treatment units.

What causes defoamer-induced oil floating and whitening?
Using defoamers to bleach oil is a highly problematic issue, as it often indicates poor defoamer quality and can lead to adverse effects in severe cases. Many customers adopt a straightforward approach: assessing whether the defoamer used for oil bleaching is excessively aggressive. Accordingly, the following section summarizes several methods employed by silicone‑based defoamer manufacturers to determine if a defoamer will cause oil bleaching.

Silicone-based defoamer production processes and applications?
Silicone-based defoamers are surfactants produced through the reaction of hydroxyl or amino groups in silicone compounds. They exhibit excellent defoaming performance and good stability, making them widely used for foam control in industrial processes. This article provides a detailed overview of silicone defoamers, focusing on both their production processes and applications.

Applications of Silicone Defoamers
Silicone compounds are polysiloxanes, indispensable raw materials in cosmetic formulation; accordingly, silicone‑based defoamers are widely used in the daily‑chemical industry. Moreover, their widespread acceptance across various sectors stems from their outstanding properties—such as chemical inertness, non‑toxicity, and environmental friendliness—ensuring they do not pollute the environment.

What are the characteristics of silicone-based defoamers?
1. With low surface tension, dimethyl silicone oil exhibits a higher surface tension than water. Its surface tension is lower than that of aqueous surfactant solutions and typical oil solutions, resulting in strong defoaming performance; the recommended dosage is 5–200 ppm (based on active content).
