Polydimethylsiloxane (PDMS) belongs to a group of polymeric
organosilicon compounds that are commonly referred to as
silicones. PDMS is the most widely used
silicon-based
organic polymer, and is particularly known for its unusual
rheological (or flow) properties. PDMS is optically clear, and, in general, inert, non-
toxic, and non-
flammable. It is also called
dimethicone and is one of several types of
silicone oil (
polymerized siloxane). Its applications range from contact lenses and medical devices to
elastomers; it is also present in shampoos (as dimethicone makes hair shiny and slippery), food (antifoaming agent),
caulking,
lubricants,
kinetic sand, and heat-resistant tiles.
