Product Details

Silicone oil CAS#63148-62-9

Silicone oil having a silica structure and is liquid at room temperature and is called as siloxane, referred as silicone oils. The simplest polydimethylsiloxane is as formula [1]. In [2], if the R, R1, R2 are all methyl groups, it is called α, ω-trimethylsilyloxy polydimethylsiloxane, that’s the commonly called silicone oil. It is a linear polymer of a low molecular weight. If R1 and R2 are not a methyl group, then it is not related to this article. Silicone oil is a colorless or light yellow transparent liquid and is odorless and tasteless. It has a high boiling point and low freezing point. The silicon-oxygen bond is very stable.
