Polyvinyylialkoholt

Polyvinyl alcohol, also known as PVA or polyvinyl alcohol, is a type of synthetic polymer that is derived from polyvinyl acetate (PVA). It is a water-soluble, white, or off-white powder that is commonly used in various industrial, commercial, and household applications.

Polyvinyl alcohol is a versatile and biodegradable polymer that can take on different forms, including fibers, films, and adhesives. It is produced through the hydrolysis of polyvinyl acetate, with the removal of acetate groups to create a hydroxyl-rich polymer chain.

The properties of polyvinyl alcohol make it suitable for numerous uses, including adhesives, packaging materials, textiles, and paper coatings. Its water solubility allows it to be used in cleaning solutions, latex paints, and other wet-end applications. Additionally, its biodegradable nature and non-toxic properties make it an environmentally friendly and safe substance.

Polyvinyl alcohol is also used in fibers, films, and coatings due to its barrier properties, which prevent the passage of gas, liquids, and water. This attributes makes PVA useful in applications involving moisture protection, UV resistance, and antistatic properties.

PVA has various industrial applications including air filtration, oil and grease absorption, and its usage in the motorcycle and marine industries. In the past decade, however, there's been a notable shift towards using renewable feedstocks for PVA production.
