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.
Product features: easy to use, after use into the toilet straight flush. Good positioning, environmental protection and health. The material is skin-friendly, waterproof, bacteria-proof and cold-proof, which can effectively avoid cross infection. Waterproof splash to isolate urine, especially for pregnant women and family use is safer and healthier, each comes in a separate small package, easy to carry.
