Product Details:


Polyvinyl alcohol (PVA) is a water-soluble polymer,it is characterized by good compactness,high crystallinity,strong bonding, flexible film made of smooth, oil resistance, solvent resistance, abrasion resistance, good gas barrier properties , as well as specially treated with a water resistance, widely used.Polyvinyl alcohol on the human body non-toxic, odorless, harmless, and has a good affinity for the natural environment, not cumulative, non-polluting.

Polyvinyl alcohol film is a polyvinyl alcohol as the main body, adding modifier additives, through a special process that can be completely degraded by microorganisms in the soil green functional material. It can degrade into carbon dioxide and water in a short time, and there are improvements to land in.The biggest advantage is a water-soluble polyvinyl alcohol film, the biggest drawback is poor water resistance. The reason why poor water resistance due to the hydrophilic hydroxyl groups (-OH) with its molecule. If you can hydroxyl proper closure, connected to the water group, it can improve the water resistance of the PVA film. PVA containing hydroxyl groups, all typical reaction may occur polyols, choose the appropriate polycondensate, with the addition amount is not the case, will be able to PVA hydroxyl groups in moderately cross I make PVA form a tough three-dimensional structure, stabilized VA under wet conditions airtightness improves the ability of the water.
