Polyvinyl alcohol (PVOH, PVA, or PVAl)in construction

Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH(OH)]n. It is used in paper making, Glue, and a variety of coatings. Polyvinyl alcohol is a non-toxic, biodegradable polymer, and products that contain PVA are safe to use and safe to consume. The Environmental Working Group rated it as a low-hazard ingredient in cosmetics, and the Food and Drug Administration has approved PVA for use in food packaging and pharmaceutical applications.

Its largest application in China is its use as a protective colloid to make polyvinyl acetate dispersions (RDP). In Japan its major use is the production of vinylon fiber. It is widely used in Glue, Wall putty/Skim Coat, Tile adhesive /Tile grout ects. PVA can dissolve quickly, even in cold water. After PVA film dissolves, any of the 55 types of microorganisms present in wastewater treatment systems can break down what’s left of the dissolved film.
