Polyvinyl alcohol (PVA) is a water-soluble polymer, which is characterized by good compactness, high crystallinity, strong adhesion, flexible and smooth film, oil resistance, solvent resistance, wear resistance, good gas permeability, and water resistance after special treatment. It is widely used.
Polyvinyl alcohol is non-toxic, tasteless, and harmless to the human body. It has a good affinity with the natural environment, with no accumulation, and no pollution.
Polyvinyl alcohol film is a green environmental protection functional material with polyvinyl alcohol as the main body, modifier, and other additives, which can be completely degraded by microorganisms in the soil after special processing. It can be degraded into carbon dioxide and water in a short time and can improve the land.
The biggest advantage of the polyvinyl alcohol film produced by China Plastic Extruder manufacturer is water solubility, and the biggest disadvantage is poor water resistance. The poor water resistance is due to the hydrophilic hydroxyl group (-OH) in its molecule. If the water resistance of the PVA film can be properly blocked and linked with water-resistant groups, the water resistance of the PVA film can be improved.
PVA contains hydroxyl groups, which can produce all typical reactions of polyols. With appropriate polycondensation, it can properly interact with the hydroxyl groups in PVA when the addition amount is small, so as to form a strong and tough three-dimensional structure of PVA, stabilize the airtightness of PVA under wet conditions and improve the water resistance.
