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. For medical and domestic applications, a process was developed in which the chlorine atoms in the silane precursor were replaced with acetate groups. In this case, the polymerization produces acetic acid , which is less chemically aggressive than HCl. As a side-effect, the curing process is also much slower in this case. The acetate is used in consumer applications, such as silicone caulk and adhesives. Silane precursors with more acid-forming groups and fewer methyl groups, such as methyltrichlorosilane , can be used to introduce branches or cross-links in the polymer chain. Under ideal conditions, each molecule of such a compound becomes a branch point. This can be used to produce hard silicone resins. In a similar manner, precursors with three methyl groups can be used to limit molecular weight, since each such molecule has only one reactive site and so forms the end of a siloxane chain.

When the load itself is removed, the strain is slowly recovered rather than instantaneously.

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.
