Polisiloxanos, di-Me, terminados en hidroxilo

Descripción:
Polisiloxanos, di-Me, terminados en hidroxilo, comúnmente conocido como polidimetilsiloxano terminado en hidroxilo (PDMS), es una clase de polímeros de silicona caracterizados por sus unidades de siloxano (Si-O) que se repiten. Estos compuestos suelen exhibir una estructura lineal con grupos metilo (Me) unidos a los átomos de silicio y grupos hidroxilo (–OH) en los extremos terminales. Esta estructura confiere propiedades únicas, incluyendo flexibilidad, baja tensión superficial y excelente estabilidad térmica, lo que los hace adecuados para una variedad de aplicaciones. A menudo se utilizan como intermedios en la síntesis de elastómeros de silicona, selladores y recubrimientos debido a su capacidad para formar enlaces fuertes con otros materiales. Además, su naturaleza hidrofóbica y baja toxicidad los hacen valiosos en formulaciones cosméticas y aplicaciones médicas. La presencia de grupos hidroxilo permite una mayor modificación química, mejorando su versatilidad en varios procesos industriales. En general, los polisiloxanos con esta estructura específica son fundamentales en muchos campos, incluyendo la ciencia de materiales, la farmacéutica y los productos de consumo.

    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.
