Polydimethylsiloxane (PDMS) is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties. Its applications range from contact lenses and medical devices to elastomers, caulking, lubricating oils and heat resistant tiles. PDMS is optically clear, and is generally considered to be inert, non-toxic and non-flammable.

OBS

poly(dimethylsiloxane): form recommended by the IUPAC (International Union of Pure and Applied Chemistry) for the systematic name corresponding to the CAS number indicated on the present record.

OBS

The chemical formula for PDMS is (C2H6OSi)n or (H3C)3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [SiO(CH3)2] units.

OBS

Also known under a large number of commercial designations, among which: AF 75, AK 100, Antaphron NM 42, Antifoam A Spray 260, Antifoam FD 62, Aquasil E, AV 1000, Baysilon, DC 360, Dow Corning 200.

OBS

alpha; omega: These words must be replaced by the corresponding Greek characters or italicized.

PHR

Methyl end-blocked polydimethylsiloxane, trimethoxysilyl terminated polydimethylsiloxane.

PHR

Dimethylpolysiloxane hydrolyzate.
