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.
