Properties of GOHSENOL
- Water-solubility
- The water-solubility of PVOH (GOHSENOL) varies depending on its grade.
Generally, a grade of a lower viscosity tends to dissolve more rapidly in water. However, the water-solubility of PVOH heavily depends on its saponification degree.
- Solvent Resistance
- GOHSENOL products are softened by or dissolved in an acid or alkali. However, they do not dissolve in most organic solvents, animal and plant oils, or greases.
- Surface Activity
- The surface tension of an aqueous solution of partially saponified PVOH is lower than that of fully saponified PVOH.
- Bonding Strength
- An aqueous PVOH (GOHSENOL) solution exhibits extremely good bonding strength with base materials that have more porous or hydrophilic surfaces, such as textiles, paper or wooden materials.
- Membrane Forming Properties
- A film made of PVOH (GOHSENOL) boasts excellent clarity, gas barrier properties, anti-clouding properties, solvent resistance, antistatic properties, water vapor permeability, etc.
- Chemical Reactivity
- GOHSENOL products are stable polymer compounds, and usually do not develop putrefaction, decomposition or polymerization when left to stand alone. In the presence of a catalyst, they will exhibit various chemical reactions.
- Safety
- PVOH (GOHSENOL) products are free from acute toxity, carcinogenicity and mutagenicity. They are highly safe chemical substances having little toxicity.
