| Section2 = }} Polydimethylsiloxane (PDMS) belong to a group of polymeric organosilicon compounds which are commonly referred to as silicones. PDMS's the most widely used silicon-based organic polymer, and's particularly known for its unusual rheological (or flow) properties. Its applications range from contact lenses and medical devices to elastomers, in shampoos (as dimethicone makes hair shiny and slippery), caulking, lubricating oils and heat resistant tiles. PDMS's optically clear, and's… (More on Polydimethylsiloxane)
