Description
- Compositon / Information on Material
REGENERATED CELLULOSE Made from natural cellulose (cotton (inters) by dissolving it in special inorganic solvents and reforming the polymer by removing the solvent to form tubular membranes. The material has the elastic and flaccid characteristics of a gel when wet with water. Regenerated cellulose, like its parent native cellulose, is quite resistant to organic solvents, elevated temperatures and extremes of Ph.
There arc no hazardous ingredients and no special handling will be required.
2′ Storage
The material should be kept away from direct sunlight, extremes of temperature and very low humidity. When not in use the membrane should be kept sealed in the bag supplied.
