Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication. [1] [2] It is particularly known for its unusual rheological (or flow) properties. See more Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones and siloxane. … See more PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid, similar to honey. However, at short flow times (or low temperatures), it acts like an elastic solid, similar to rubber. Viscoelasticity is a form of nonlinear … See more Surfactants and antifoaming agents PDMS is a common surfactant and is a component of defoamers. PDMS, in a modified form, is used as an herbicide penetrant and … See more • Silicone • Cyclomethicone • Siloxane and other organosilicon compounds • Polymethylhydrosiloxane (PMHS) • Silicone rubber See more The chemical formula of PDMS is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [Si(CH3)2O] units. Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: n Si(CH3)2Cl2 + (n … See more PDMS is hydrophobic. Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air plasma and argon plasma will work for this application. This treatment renders the PDMS surface hydrophilic, … See more According to Ullmann's Encyclopedia, no "marked harmful effects on organisms in the environment" have been noted for siloxanes.
