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. PDMS is optically clear and, in general, inert, non … Prikaži več 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. … Prikaži več 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 … Prikaži več 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 is a critical ingredient in water-repelling coatings, such as Rain-X. Hydraulic fluids … Prikaži več • Silicone • Cyclomethicone • Siloxane and other organosilicon compounds • Polymethylhydrosiloxane (PMHS) • Silicone rubber Prikaži več 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 … Prikaži več PDMS is hydrophobic. Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air … Prikaži več According to Ullmann's Encyclopedia, no "marked harmful effects on organisms in the environment" have been noted for siloxanes.
