PDMS definition of PDMS by Medical dictionary

SpletAbstract Polydimethylsiloxane (PDMS) is commonly used in medical devices because it is non-toxic and stable against oxidative stress. Relatively high blood platelet adhesion and the need for chemical crosslinking through curing, however, limit its utility. SpletPolydimethylsiloxane (PDMS) is the simplest member of silicone family. Lower molecular weight- exist as liquid used in lubricants, antifoaming agents and hydraulic fluid. Previously famous for its usage as breast implants. Higher molecular weight- soft compliant rubber or resin. Used as caulks, sealants and putty. SpletPDMS was initially bonded to itself (Duffy et al., 1998a) by plasma oxidation of its surfaces.
