What is the relationship between silicone defoamer and dimethyl silicone oil? Dimethicone and silicone defoamer have certain similarities. Let’s take a closer look at the two products and see the relationship between them.


1. Defoaming agent is an auxiliary agent whose function is to eliminate foam formed by materials during the production process.

2. The main component of silicone defoamer is silicone oil. Silicone oil is a non-volatile oily liquid at room temperature. It is insoluble in water, animal and vegetable oils and mineral oils, or has very little solubility. It can withstand both high temperatures and Low temperature. It is chemically inert, physically stable and has no biological activity.

3. Silicone defoamer is a white, viscous emulsion. It can not only remove foam on the liquid surface of the process medium in the production process, thereby improving the separation, gasification, drainage and other effects of filtration, washing, extraction, distillation, evaporation, dehydration, drying and other processes, ensuring that all types of materials are contained and processed The capacity of the container.

4. Polydimethylsiloxane, also called dimethicone, is a hydrophobic silicone material. It is used in various fields such as medicines, daily chemicals, food, and construction, and its derivatives have reached hundreds of species.

5. Dimethicone is a colorless or light yellow liquid, odorless, highly transparent, heat-resistant, cold-resistant, with small viscosity changes with temperature, waterproof, small surface tension, thermal conductivity, non-toxic, odorless, and physiologically inert. , good chemical stability. It has good electrical insulation, weather resistance, hydrophobicity and high shear resistance. It has excellent physical properties and can be directly used in moisture-proof insulation, damping, shock absorption, defoaming, lubrication, polishing, etc. It is widely used as insulation lubrication, shockproof, oil dust proof, dielectric fluid and heat carrier. And used as defoaming, release agent, paint and daily chemical additives.

The relationship between the two is that dimethyl silicone oil is the raw material of silicone defoaming agent. Dimethyl silicone oil can be used as a defoaming agent, but the defoaming agent can only be used as a defoaming agent.
