Packing: 25kg/pp bag lined with plastics, 25mt /20’FCL
Properties: PVA series product are non-toxic , smellles and pollution – free white crystals of floc or particles or powder , dissolvable in 80~90°C water .PVA aqueous solution has good adhesive performance and film – foaming function , and good resistant to most organic solvents such as oil .lubrication agent and hydrocarbons ;Chemical reaction properties such as esterification , etherification and acetalation are as same as those of polyhydric alcohol with long carbon chains .
Uses: Preparation of is the largest use for polyvinyl alcohol in the U. S. And western Europe. Its use as a polymerization aid is the largest market in China. In Japan the major use is vinylon fiber production.
Some other uses of polyvinyl alcohol include:
1. Adhesive and thickener material in latex paints, paper coatings, hairsprays, shampoos and glues.
2. Textile agent
3. Barrier in (PET) bottles.
4. For use as synthetic vessels in flow testing.
5. Movie and children's play or slime when combined with.
6. Feminine hygiene and adult incontinence products as a plastic backing sheet.
7. As a because materials such as 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
11. Used with polyvinyl acetate to make Elmer's glue
12. Used in eye drops and hard solution as a lubricant.
13. Used in protective chemical-resistant gloves
14. Used as a for specimen collection, especially stool samples
15. When doped with iodine, PVA can be used to polarize light.
16. As an agent in medical procedures
