Description:

Polyvinyl alcohol (PVA) is a synthetic polymer that is known for its water solubility, colorless and odorless nature. It is created by dissolving polyvinyl acetate in alcohol with an alkaline catalyst, a process called hydrolysis or alcoholysis. PVA is widely used in various applications, including textiles, paper, packaging, and medical products.
