Polysiloxane, di-Me, hydroxy-terminiert

Beschreibung:

Polysiloxane, di-Me, hydroxy-terminiert, allgemein bekannt als hydroxylterminierter Polydimethylsiloxan (PDMS), ist eine Klasse von Silikonpolymeren, die durch ihre sich wiederholenden Siloxaneinheiten (Si-O) gekennzeichnet sind. Diese Verbindungen weisen typischerweise eine lineare Struktur mit Methylgruppen (Me) auf, die an die Siliziumatome gebunden sind, und Hydroxylgruppen (–OH) an den Enden. Diese Struktur verleiht einzigartige Eigenschaften, darunter Flexibilität, niedrige Oberflächenspannung und hervorragende thermische Stabilität, was sie für eine Vielzahl von Anwendungen geeignet macht. Sie werden häufig als Zwischenprodukte bei der Synthese von Silikonelastomeren, Dichtstoffen und Beschichtungen verwendet, da sie in der Lage sind, starke Bindungen mit anderen Materialien zu bilden. Darüber hinaus machen ihre hydrophoben Eigenschaften und ihre geringe Toxizität sie in kosmetischen Formulierungen und medizinischen Anwendungen wertvoll. Das Vorhandensein von Hydroxylgruppen ermöglicht eine weitere chemische Modifikation, die ihre Vielseitigkeit in verschiedenen industriellen Prozessen erhöht. Insgesamt sind Polysiloxane mit dieser spezifischen Struktur in vielen Bereichen, einschließlich Materialwissenschaften, Pharmazie und Konsumgütern, von zentraler Bedeutung.

DMS-S51: Silanol Terminated PDMS, 90,000-150,000 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.
