PVA 0899 Application
It is a low viscosity, fully hydrolyzed polyvinyl alcohol grade product with high purity, ultrafine film-forming properties, and excellent water solubility. It has excellent film-forming properties, transparent film, high mechanical strength, and low moisture absorption.
Used for medicinal film and outer medicinal substrate
It is a high-purity, pharmaceutical-grade PVA material with low impurity content and safe biocompatibility. It forms a super-smooth, uniform, and flexible water-soluble film with stable solubility and no chemical reactions with drug components. Widely used as an external coating substrate for pharmaceutical soluble film carriers and drug formulations, ensuring hygienic, stable, and safe drug packaging and surface protection.
