Polisilossani, di-Me, terminati con idrossile

Descrizione:

Polisilossani, di-Me, terminati con idrossile, comunemente noto come polidimetilsilossano terminato in idrossile (PDMS), è una classe di polimeri di silicone caratterizzati dalle loro unità di silossano (Si-O) che si ripetono. Questi composti presentano tipicamente una struttura lineare con gruppi metilici (Me) attaccati agli atomi di silicio e gruppi idrossile (–OH) alle estremità terminali. Questa struttura conferisce proprietà uniche, tra cui flessibilità, bassa tensione superficiale e ottima stabilità termica, rendendoli adatti a una varietà di applicazioni. Sono spesso utilizzati come intermedi nella sintesi di elastomeri di silicone, sigillanti e rivestimenti grazie alla loro capacità di formare legami forti con altri materiali. Inoltre, la loro natura idrofobica e bassa tossicità li rendono preziosi nelle formulazioni cosmetiche e nelle applicazioni mediche. La presenza di gruppi idrossile consente ulteriori modifiche chimiche, migliorando la loro versatilità in vari processi industriali. In generale, i polisilossani con questa struttura specifica sono fondamentali in molti campi, tra cui la scienza dei materiali, la farmaceutica e i prodotti di consumo.

DMS-S35: Silanol Terminated PDMS, 5,000 cSt (Telechelic Functional Fluid)
Terminal silanol groups render polydimethylsiloxanes susceptible to condensation under both mild acid and base conditions. They are intermediates for most room temperature vulcanizeable (RTV) condensation cure silicones. The reactivity of silanol fluids is utilized in applications other than RTVs. Low viscosity silanol fluids are employed as filler treatments and structure control additives in silicone rubber compounding. Intermediate viscosity (1,000-10,000 cSt) fluids can be applied to textiles as durable fabric softeners. High viscosity silanol terminated fluids form the matrix component in tackifiers and pressure sensitive adhesives.
