Product Description

High Quality Polydimethylsiloxane PDMS CAS No.: 9006-65-9

1.Chemical Name: Polydimethylsiloxane PDMS

Polydimethylsiloxane is a hydrophobic organic silicon material, also known as dimethyl silicone oil.

It has been applied in various fields such as pharmaceuticals, daily chemical products, food, and construction, with hundreds of derivatives. The commonly used polysiloxanes mainly include: polydimethylsiloxane, cyclomethylsiloxane, aminosiloxane, polymethylphenylsiloxane, and polyether polysiloxane copolymer. Cyclopolydimethylsiloxane is one of the commonly used polysiloxanes. This product is non-toxic, but it may cause vascular embolism and brain damage in clinical practice.

2.Description: as an anti-foam agent

3.Appearance: transparent, liquid, colorless

4.Other Information: 

The most commonly used silicone defoamer is polydimethylsiloxane, also known as dimethicone. It has low surface energy, low surface tension, low solubility in water and general oil, and high activity. Its main chain is a silicon-oxygen bond, which is a non-polar molecule. It has no affinity with polar solvent water, and has little affinity with general oils. It has low volatility and chemical inertness, relatively stable and low toxicity. Pure polydimethylsiloxane is difficult to be used as a defoamer without dispersion treatment. It may be due to its high interfacial tension with water and low spreading coefficient, which makes it difficult to disperse on the foaming medium. Therefore, the silicone oil is mixed into SiO2 aerosol to form a composite, that is, the hydrophobically treated SiO2 aerosol is mixed into dimethyl silicone oil and processed at a certain temperature and a certain period of time, and then it can be prepared.
