(polyvinyl alcohol 4 88)
A: Polyvinyl Alcohol 4-88 (PVA 4-88) is a water-soluble polymer with a hydrolysis degree of 87-89% and a molecular weight of ~31,000. It is widely used in adhesives, coatings, and films due to its excellent film-forming and binding properties.
A: Polyvinyl Alcohol (PVA) is a water-soluble polymer derived from the hydrolysis of Polyvinyl Acetate (PVAc). PVAc is non-water-soluble and used in adhesives, while PVA is utilized in films, textiles, and emulsifiers due to its solubility and flexibility.
A: Dissolve PVA in hot water (80-90°C) while stirring to create a clear solution. Adjust the concentration (typically 5-10%) based on desired viscosity. Apply the cooled solution as an adhesive for paper, wood, or textiles.
A: PVA is used in water-soluble films, adhesives, textile sizing, and as a binder in cosmetics and pharmaceuticals. It also serves as a release agent in mold-making and a stabilizer in emulsion polymerization.
A: PVA 4-88 has a specific hydrolysis degree (87-89%) and molecular weight (~31,000), offering balanced solubility and film strength. Lower hydrolysis grades (e.g., PVA 1788) dissolve faster in cold water, while higher grades provide greater chemical resistance.
