What is PVA ? 


Polyvinyl alcohol, also known as PVOH, PVA, or PVAL, is a synthetic polymer that is soluble in water. It is effective in film forming, emulsifying, and has an adhesive quality. It has no odor and is not toxic, and is resistant to grease, oils, and solvents. It is ductile but strong, flexible, and functions as a high oxygen and aroma barrier.



What Is It Used For?

Polyvinyl alcohol is widely used to strengthen textile yarn and papers, particularly to make the latter more resilient to oils and grease. It is also used in freshwater sports fishing. PVA is added into bags that are filled with oil-based or dry fishing bait and attached to the hook. As PVA is soluble in water, when the bag lands on the bed of the water, it breaks down, leaving the hook bait surrounded by pellets and ground bait. This attracts fish to the hook bait, although the PVA does cause the plastic to dissolve in water.

PVA may also be used as a coating agent for food supplements and does not pose any health risks as it is not poisonous. One of the leading industrial uses for PVA is for food packaging, accounting for 31.4 percent of the global share in 2016. To combat moisture formation from foodstuff, PVA film is created to be thin and water-resistant. Its crosslinking density and resistance to moisture are added benefits to its usability in this area.


How is this Resin Made?

There are two ways in which the 4% aqueous solution of Polyvinyl alcohol (PVA) may be created. The first uses a conventional heating method, the second uses the microwave heating method. The latter is easier to conduct and is less time-consuming. Once the 4% PVA solution is made, it can last between 6 and 8 weeks. Generally, it is advisable to refrigerate this solution, which supports the growth of bacteria.

When making the Polyvinyl alcohol solution, it is recommended to use tap water, as bacteria grows faster in PVA containing distilled water
