Polissiloxanos, di-Me, terminados em hidroxilo

Descrição:

Polissiloxanos, di-Me, terminados em hidroxilo, comumente referido como polidimetilsiloxano terminado em hidroxila (PDMS), é uma classe de polímeros de silicone caracterizados por suas unidades de siloxano (Si-O) que se repetem. Esses compostos geralmente exibem uma estrutura linear com grupos metila (Me) ligados aos átomos de silício e grupos hidroxila (–OH) nas extremidades terminais. Essa estrutura confere propriedades únicas, incluindo flexibilidade, baixa tensão superficial e excelente estabilidade térmica, tornando-os adequados para uma variedade de aplicações. Eles são frequentemente usados como intermediários na síntese de elastômeros de silicone, selantes e revestimentos devido à sua capacidade de formar ligações fortes com outros materiais. Além disso, sua natureza hidrofóbica e baixa toxicidade os tornam valiosos em formulações cosméticas e aplicações médicas. A presença de grupos hidroxila permite uma maior modificação química, aumentando sua versatilidade em vários processos industriais. No geral, os polisiloxanos com essa estrutura específica são integrais em muitos campos, incluindo ciência dos materiais, farmacêutica e produtos de consumo.

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.
