CAS 70131-67-8: 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.
