MgTube
(Microtubular Basic Magnesium Carbonate)

MgTube is a microtubular particle with a unique morphology which has a porous shell.


MgTube can be applied as functional microcapsule by means of impregnation of liquid into microtubular structure or release of impregnated matter.

Features

  • Liquid can be powderized by its impregnation into MgTube.
  • MgTube can be used as a carrier with release sustainability which release impregnated matter gradually.
  • Impregnated component in MgTube can be released by compression force or acid stimulus.
  • MgTube can be applied as an adsorbent or absorbent using its porous structure.
