What is the Nichigo G-polymer™?

Nichigo G-polymer™ is water soluble resin based on polyvinyl alcohol modified with butenediol, which has excellent gas barrier property, compostability, and extrudability.

Water Solubility and Extrudability Characteristics

Compared to conventional PVOH, Nichigo G-polymer™ has excellent water solubility (dissolves even at room temperature). It has a wider range of temperatures at which it can be melt-molded and has excellent extrudability.

Water Solubility Characteristics:

	Solubility condition(Temperature/time)
	20℃/2hrs	90℃/1hr
Nichigo G-Polymer™	Dissolved	Dissolved
Ref. fully hydrolyzed PVOH	Partially dissolved	Dissolved

 

Extrudability Characteristics:

 

Gas Barrier Property

Gas barrier property of Nichigo G-Polymer™ depends on humidity. It is especially suitable for dry condition.

Orientability

Nichigo G-Polymer™ film has excellent orientation characteristics.

Resins	Temperature (°C）	Orientation ratio (times)
