Poly(vinyl alcohol), MW 25000, 88% hydrolyzed

Poly(vinyl alcohol) (PVA) is a water-soluble synthetic polymer derived from polyvinyl acetate (PVAc) via hydrolysis. The degree of hydrolysis determines its solubility, crystallinity, and hydrogen bonding potential, making PVA highly versatile in both industrial and biomedical applications. It features excellent film-forming ability, chemical resistance, biocompatibility, and mechanical strength, which makes it a preferred material for coatings, adhesives, hydrogels, and packaging films. Additionally, its ability to form strong intermolecular hydrogen bonds enhances moisture retention and structural integrity, making it useful for applications requiring controlled permeability and water interaction.
Higher hydrolysis grade products require progressively more energy to dissolve because of their greater degree of crystallinity.

Applications:

Pharmaceutical & Biomedical Applications: Used in drug delivery systems, wound dressings, and contact lens materials due to its biocompatibility and ability to form hydrogels.

Adhesives & Binders: Serves as a water-soluble adhesive in paper, textile, and wood industries, offering strong adhesion with biodegradability.

Packaging Films & Coatings: Used for biodegradable and water-soluble films in food and pharmaceutical packaging, ensuring controlled moisture barrier properties.

Textile & Paper Processing: Functions as a sizing agent and surface treatment polymer, improving fiber strength and resistance to wear.

Emulsion Polymerization & Stabilization: Acts as a protective colloid in polymerization processes, aiding in the production of stable emulsions and dispersions.
