Description

Cuprammonium Cellulose is a specialized cellulose derivative produced by dissolving cellulose in a cuprammonium hydroxide solution, resulting in a regenerated cellulose material with unique properties. This compound is valued for its ability to form exceptionally fine, strong, and uniform fibers and films with high tensile strength and a smooth, silk-like luster. It is a critical material for manufacturers in the textile, medical, and membrane technology sectors seeking advanced cellulose-based solutions for high-performance applications.

Application

• Production of high-tenacity Cuprammonium Rayon (Cupro) fibers for premium textiles and linings.
• Manufacture of hemodialysis membranes and other medical filtration devices due to its biocompatibility.
• Used in the creation of regenerated cellulose films for packaging and specialty coatings.
• Formulation of viscose sponge and other absorbent medical and cosmetic products.
• Base material for chromatography supports and laboratory filter media.
• Research and development of advanced composite materials and battery separators.
