Polysiloxanes, di-Me, terminés par hydroxy

Description :

Polysiloxanes, di-Me, terminés par hydroxy, communément appelé polydiméthylsiloxane terminal hydroxyle (PDMS), est une classe de polymères siloxanes caractérisés par leurs unités de siloxane (Si-O) répétées. Ces composés présentent généralement une structure linéaire avec des groupes méthyle (Me) attachés aux atomes de silicium et des groupes hydroxyle (–OH) aux extrémités terminales. Cette structure confère des propriétés uniques, notamment la flexibilité, une faible tension superficielle et une excellente stabilité thermique, ce qui les rend adaptés à une variété d'applications. Ils sont souvent utilisés comme intermédiaires dans la synthèse d'élastomères de silicone, de scellants et de revêtements en raison de leur capacité à former des liaisons fortes avec d'autres matériaux. De plus, leur nature hydrophobe et leur faible toxicité les rendent précieux dans les formulations cosmétiques et les applications médicales. La présence de groupes hydroxyles permet une modification chimique supplémentaire, améliorant leur polyvalence dans divers processus industriels. Dans l'ensemble, les polysiloxanes avec cette structure spécifique sont essentiels dans de nombreux domaines, y compris la science des matériaux, la pharmacie et les produits de consommation.

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.
