*Required Fields
The Poly(vinyl alcohol), with the CAS registry number 9002-89-5, is also known as Partially hydrolysed polyvinyl alcohol. It belongs to the product categories of Polymer Science;Polymers;Vinyl Alcohols.This chemical's molecular formula is (C2H4O)n.What's more,Its systematic name is Polyvinyl alcohol.It is a polymer prepared from polyvinyl acetates by replacement of the acetate groups with hydroxyl groups. It is used as a pharmaceutic aid and ophthalmic lubricant as well as in the manufacture of surface coatings artificial sponges, cosmetics, and other products.Consumption of Poly(vinyl alcohol) was over one million metric tons in 2006.Larger producers include Kuraray (Japan and Europe) and Celanese (USA) but mainland China has installed a number of very large production facilities in the past decade and currently accounts for 45% of world capactity.It should be Store in a tightly closed container,and be cool, dry, well-ventilated area away from incompatible substances.
Safety Information of Poly(vinyl alcohol):
The Poly(vinyl alcohol) is Toxic by inhalation, in contact with skin and if swallowed. It is irritating to eyes and skin and danger of very serious irreversible effects. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. When you use it ,wear suitable protective clothing and gloves. Avoid contact with skin and eyes. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) .
Some uses of Poly(vinyl alcohol) include:
(1)Adhesive and thickener material in latex paints, paper coatings, release liner, hairsprays, shampoos and glues; (2)T.extile sizing agent; (3)Carbon dioxide barrier in polyethylene terephthalate (PET) bottles; (4)Carotid phantoms for use as synthetic vessels in doppler flow testing; (5)Movie practical effect and children's play putty or slime when combined with borax; (6)Feminine hygiene and adult incontinence products as a biodegradable plastic backing sheet; (7)As a mold release because materials such as epoxy do not stick to it; (8)As a water-soluble film useful for packaging; (9)As fiber reinforcement in concrete; (10)As a surfactant for the formation of polymer encapsulated nanobeads.
