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.
- 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.
