PVA (Polyvinyl Alcohol) 092-20 refers to a specific grade of PVA that is fully hydrolyzed. Polyvinyl alcohol is a synthetic polymer derived from vinyl acetate through a process called hydrolysis, which removes the acetate groups and replaces them with alcohol (hydroxyl) groups. The degree of hydrolysis determines the properties of the PVA, including its solubility and strength.

In the case of PVA 092-20, it is considered a full hydrolyzed grade, which means that a high percentage of the acetate groups have been replaced with hydroxyl groups, resulting in a highly hydrophilic material. Full hydrolysis typically refers to a PVA with a degree of hydrolysis of 98% or higher, meaning that more than 98% of the acetate groups have been converted to alcohol groups.

PVA 092-20 is known for its excellent water solubility and film-forming properties. It is commonly used in a wide range of applications, including adhesives, coatings, textiles, paper coatings, packaging films, and as a component in various water-soluble products such as laundry bags, detergent pods, and water-soluble films.

Due to its fully hydrolyzed nature, PVA 092-20 exhibits high tensile strength, transparency, and biodegradability. These properties make it suitable for applications where water solubility and temporary barriers are required, such as in the packaging industry, where PVA films can dissolve in water, leaving no residue or environmental pollution.
