（1）Water solubility: The water solubility of different grades of Gohsenol products is different. Generally, products with low viscosity dissolve faster in water. However, the water solubility of PVA largely depends on its alcoholysis.
（2）Solvent resistance: Gohsenol products can be softened or dissolved in acid or lye. However, our products do not dissolve in most organic solvents, vegetable and animal oils or fats.
（3）Surface activity: the surface tension of the aqueous solution of partially alcoholized PVA is lower than that of the aqueous solution of completely alcoholized PVA. ④ Bonding strength: for multi porosity or hydrophilic surface substrate, such as textiles, paper or wood materials, Gohsenol aqueous solution has super bonding strength.
（4）Film performance: the film made of Gohsenol has excellent clarity and air resistance, anti-fog, solvent resistance, antistatic, moisture permeability and so on.
Chemical reactivity: Gohsenol products are stable polymer compounds, in separate storage, usually do not occur corruption, degradation or polymerization. When catalysts are added, various chemical reactions occur in the products.
（5）Safety: Gohsenol products do not exist acute toxicity, carcinogenicity and mutagenicity, it is a very low toxicity, high safety of synthetic resin.
