Enhancing Construction Materials with Polyvinyl Alcohol and Polypropylene Fiber

 

La HPMC es un polímero que se utiliza, entre otras cosas, como un agente espesante y formador de película. En la oftalmología, se valora principalmente por su capacidad para aumentar la viscosidad de las soluciones acuosas, lo que reduce la evaporación y mejora la lubricación ocular. Esto la convierte en una elección ideal para pacientes que sufren de ojo seco o que requieren una hidratación adicional debido a condiciones específicas.
