Research on PVA properties and some applications for common uses

·         Paper adhesive with boric acid in spiral tube winding and solid board production
·         Thickener, modifier, in polyvinyl acetate glues
·         Textile sizing agent
·         Paper coatings, release liner,
·         As a water-soluble film useful for packaging. An example is the envelope containing laundry detergent in "liqui-tabs".
·         Feminine hygiene and adult incontinence products as a biodegradable plastic backing sheet.
·         Carbon dioxide barrier in polyethylene terephthalate (PET) bottles
·         As a film used in the water transfer printing process
·         As a form release because materials such as epoxy do not stick to it
·         Movie practical effect and children's play putty or slime when combined with borax
·         Used in eye drops (such as artificial tears to treat dry eyes) and hard contact lens solution as a lubricant
·         PVA fiber, as reinforcement in concrete
·         Raw material to polyvinyl nitrate (PVN). an ester of nitric acid and polyvinyl alcohol.
·         As a surfactant for the formation of polymer encapsulated nanobeads
·         Used in protective chemical-resistant gloves
·         Used as a fixative for specimen collection, especially stool samples
·         When doped with iodine, PVA can be used to polarize light
·         As an embolization agent in medical procedures
·         Carotid phantoms for use as synthetic vessels in Doppler flow testing
·         Used in 3D printing as support structure that can then be dissolved away.
