Features of GOHSENOL™

GOHSENOL™ has the following eight features.

Water Solubility

Lower viscosity grades usually dissolve more easily. Solubility also substantially varies depending on the degree of saponification.
* Water solubility of GOHSENOL™ varies by grade.
Solvent Resistance

The product does not dissolve in most organic solvents, animal or vegetable oils, or greases.
Surface Activity

An aqueous solution of partially saponified PVOH has a lower surface tension than fully saponified PVOH.
Bonding Strength

Aqueous solutions of GOHSENOL™ exhibit extremely high bonding strength with materials that have porous and hydrophilic surfaces, such as fabric, paper, and wood.
Film Forming Properties

Films made of GOHSENOL™ boast excellent features including transparency, gas barrier performance, anti-fog properties, solvent resistance, antistatic properties, and moisture permeability.
Chemical Reactivity

GOHSENOL™ products are stable polymer compounds and usually do not putrefy, decompose, or polymerize on their own. In the presence of specific catalysts, it exhibits various chemical reactions.
Safety and Biodegradability

GOHSENOL™ is an eco-friendly biodegradable resin. The product has been registered on the “GreenPla” positive list by the Japan BioPlastics Association.
Gas Barrier Performance

GOHSENOL™ exhibits extremely high impermeability to various gases at low humidity, including oxygen, nitrogen, hydrogen, carbon dioxide, and helium.
