Organic Silicone , normally Chemical Organic Silicium which is known as Organic Silicone Chemicals, or Organosilicone Chemicals, are silicone compounds that contain Si-O bonds and have at least one organic group directly connected to a silicon atom.
Organic Silane / Silane Chemicals , or Organic Silane Chemicals the compound of silicon and hydrogen, is a general term for a range of Silicide Chemicals compounds, including silane (SiH4), ethyl silane (Si2H6) and some more advanced silicon hydrogen compounds.
Silicone oil or Silicone Fluid Chemicals refers to linear polysiloxane products that remain liquid at room temperature. It is divided into two Types Of Silicone Oil : methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary Silicone Based Oil , its organic groups are all methyl, and the silicone oil that uses other organic groups to replace some methyl groups is called modified silicone oil. Silicone Lubricating Oil would be most common application for the product.
