FAQS on polyvinyl alcohol

Q: What is the difference between polyvinyl alcohol and polyvinyl acetate?

A: Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer derived from polyvinyl acetate (PVAc) through hydrolysis. Unlike PVAc, which is hydrophobic and used in adhesives, PVA has excellent film-forming and biodegradable properties. Their chemical structures and applications differ significantly due to varying hydroxyl and acetate groups.

Q: How to use polyvinyl alcohol for crafting or adhesives?

A: Dissolve PVA granules in hot water (typically 10-20% concentration) while stirring until clear. Use the solution as a glue, coating, or for embedding materials. Allow it to dry completely to form a flexible, transparent film.

Q: What are the common industrial uses of polyvinyl alcohol?

A: PVA is widely used in textiles (sizing agents), paper coatings, and biodegradable packaging. It also serves as a binder in ceramics, a component in eye drops, and a release agent in mold-making due to its non-toxic and adhesive properties.

Q: Is polyvinyl alcohol safe for skin contact or food applications?

A: PVA is generally recognized as safe (GRAS) for limited skin contact and used in cosmetics/pharmaceuticals. However, industrial-grade PVA may contain impurities—only food-grade PVA should be used in edible films or medical applications.

Q: Can polyvinyl alcohol be mixed with other polymers for enhanced properties?

A: Yes, PVA is often blended with starch, cellulose, or synthetic polymers to improve strength, flexibility, or water resistance. Such mixtures are used in biodegradable plastics, drug delivery systems, and advanced coatings.
