Polydimethylsiloxane Description
Polydimethylsiloxane (PDMS) is a polymer organic silicon compound that is optically transparent and is generally considered to be inert, non-toxic and non-flammable.
Polydimethylsiloxane (PDMS) is the most widely used silicon-based organic polymer material, which is used in microfluidic systems, caulking agents, lubricants, and contact lenses in biomicroelectromechanical applications.
Dimethylsiloxane in liquid form belongs to the category of silicone oil and is generally a colorless, odorless, non-toxic, non-volatile liquid. Solid dimethylsiloxane is a silica gel, non-toxic, hydrophobic inert material, and a non-flammable, transparent elastomer.
