polivinilacetát

Polivinilacetát, often abbreviated as PVA or PVAc, is a synthetic polymer. It is a colorless, viscous liquid at room temperature and solidifies upon cooling. Polivinilacetát is produced through the polymerization of vinyl acetate monomer. This process typically involves free-radical polymerization. It is a type of thermoplastic polymer, meaning it can be softened by heat and then molded into various shapes.

Polivinilacetát is widely used as an adhesive. It is the primary component of many common household glues, such as white glue and wood glue. Its adhesive properties stem from its ability to form strong bonds with porous materials like paper, wood, and fabric. It dries clear and forms a flexible, water-resistant film. The specific properties of polivinilacetát can be modified by adjusting the molecular weight and other polymerization parameters.

Beyond adhesives, polivinilacetát finds applications in paints and coatings, where it acts as a binder. It is also used in the production of textiles and paper to improve their strength and durability. In the construction industry, it can be incorporated into cement and plaster formulations. Due to its versatility and relatively low cost, polivinilacetát remains a significant material in various industrial and consumer products.
