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.
