The stamp is produced from the normal techniques of photolithography or electron-beam lithography. Amodimethicone is the most widely used amino-modified silicone.

Polydimethylsiloxane PDMS , also known as dimethylpolysiloxane or dimethicone , is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication. It 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 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 it makes hair shiny and slippery , food antifoaming agent , caulk , lubricants and heat-resistant tiles.

Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. More information about the EC Inventory can be found here. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. If generated, an InChI string will also be generated and made available for searching. More help available here. CAS no.

Explore the versatility of Polydimethylsiloxane PDMS , its properties, applications, and environmental impact in our in-depth article. Polydimethylsiloxane, often abbreviated as PDMS, is a versatile and popular polymer used in a myriad of applications due to its unique properties. Primarily composed of silicon, oxygen, and carbon, this compound boasts remarkable flexibility and stability, making it a preferred choice in various industries. The basic structural unit of PDMS is a chain of — Si CH 3 2 -O- repeats, with silicon atoms linked by oxygen atoms — a structure that is essentially a silicon-oxygen backbone with methyl groups attached to the silicon. The dynamic nature of these silicone-oxygen bonds gives PDMS its renowned flexibility, while the non-reactive methyl groups contribute to its chemical inertness. The manufacturing of PDMS typically involves the polymerization of dimethyldichlorosilane, followed by hydrolysis and condensation reactions.
