Description
High Density Chitosan Powder is a natural biopolymer derived from chitin, predominantly sourced from squid pens, shrimp shells, crab shells, and certain fungal cell walls. Through precise deacetylation and refinement, this chitosan achieves a high density and superior purity, offering excellent solubility in acid and consistent functionality across applications. With its environmentally friendly and biodegradable nature, High Density Chitosan serves as a cornerstone material in the production of chitosan derivatives, food ingredients, agricultural biostimulants, and medical textiles. Its optimized density and controlled viscosity provide improved processing performance and uniform dispersion in both aqueous and dry formulations.
