Water Solubility (Compared to PLA)

Nichigo G-PolymerTM shows excellent water solubility even at low temperature

[Test conditions]
Sample

  • G-Polymer: Blend of powder and pellet
  • PLA: Blend of powder and pellet

1g sample / 100g RT tap water
Plugging process: Stir at medium speed for 1 hour @ RT
Dissolution process: Hold at 122/140 degree F in dryer (1, 3 days, 1, 2 weeks)

Bridging Property

Nichigo G-PolymerTM shows excellent bridging property

[Test conditions]
Slot tester
60g polymer/5g guar/1L tap water were stirred at RT for 60 minutes
Slurry was injected into tester (slot size: 0.072/0.025 inch), then pressurized 200 psi
Measure effluent thru slot, less the better
