Polyvinyl alcohol (PVA)is a water-soluble polymer.
PVA is the only vinyl polymer that can be used by bacteria as a carbon source and energy source.Underthe action of bacteria and enzymes,it can de- grade 75%in 46 days.lt is a biodegradable polymer materiathat can be mass-produced by non-petroleum routes.lt is characterized by good density, high crystallinitystrong adhesion,flexible and smooth film,oil resistance,solvent resistance,abrasion resistance,good gasbarrier properties,as well as water resistance after special treatment,and has a wide range of uses.Polyvinyl alcohol is non-toxic,odorless and harmless to the human body.lt has excellent oil resistancesolvent resistance and gas barrier properties, and has unique advantages in food and pharmaceuticalpackaging.lt has good affinity with the natural environment,does not accumulate,and has no pollutionPolyvinyl alcohol film is a green and environmentally friendly functional material that uses polyvinyl.alcohol as the main body,adds modifiers and other additives,and is processed through a special processand can be completely degraded by microorganisms in the soil.lt can be degraded into carbon dioxideand water in a short time,and has the effect ofimproving the land.
PVA is a biodegradable polymer material.
Polyvinyl alcohol (PvA) is the only vinyl polymer that can be used by bacteria as a carbon source and energy sourceUnder the action of bacteria and enzymes,it can degrade 75% in 46 days.lt belongs to biodegradable, high molecularmaterial, in the textile, food, medicine, construction, wood processing, paper and other industries have a broad applicationprospects.The water-soluble PVA film is made from partially alcoholized PVA resin with about 88% alcoholysis degree.and can be completelydeqraded.
PVA material has good biocompatibility.
PVA is a common safety film-forming agent.lt is non-toxic and has no side effects on human body.lt has good Biocompatibility, therefore, it can be used in medical mouth dissolving film, wound skin repair,tissue stem cell culture fluid, eyedrops,dish-washing beads and other products.
