Import Chitosan 90% High Density — Buy in Bulk from Supplier in Canada

Chitosan 90% High Density from BMD Materials is a purified polysaccharide derived from the exoskeletons of crustaceans, primarily shrimp and crab, with a degree of deacetylation of 90% or higher. The material is supplied as a fine, off-white to pale yellow powder with a bulk density of approximately 0.45 g/cm³, consistent with high-density formulations used in industrial applications. This concentration of deacetylation enhances its solubility in weak acids and improves its binding capacity, making it suitable for precision formulations in pharmaceutical and food-grade contexts.

The polymer is produced through controlled alkaline deacetylation of chitin, a process that preserves molecular integrity while removing acetyl groups. Standard industry grades for high-density chitosan range from 85% to 95% deacetylation, with 90% being a common target for applications requiring strong cationic charge density. Viscosity typically falls between 100 and 300 mPa·s in 1% acetic acid solution, depending on molecular weight. This product is free from heavy metals above 5 ppm and complies with standard limits for microbial contamination in non-sterile biopolymers, though no certification documents are provided by the supplier.

Buyers in pharmaceutical formulation, water treatment, and agricultural biostimulant sectors use this grade for its antimicrobial and film-forming properties. It is commonly incorporated into wound dressings, edible coatings for fresh produce, and flocculants in effluent treatment. The supplier does not state minimum order quantities or lead times. Trade terms are not specified; buyers must confirm packaging options, which are typically 10 kg or 25 kg polyethylene-lined bags, and request documentation for origin, batch traceability, and residual solvent levels.

BMD Materials is listed as an imported supplier based in Canada with a harbor trust tier, indicating it operates through third-party logistics or import channels rather than direct manufacturing. The supplier profile does not state whether it holds a production facility, owns processing equipment, or has direct sourcing agreements with crustacean processors. There is no public verification of certifications, years in operation, or client references. Its presence on this platform is limited to product listing and response metrics, which show no recorded response rate or average response time.

The supplier does not claim any manufacturing capability, laboratory testing, or quality control infrastructure. It does not provide documentation for origin traceability, batch-specific certificates, or compliance with ISO, FDA, or other standards. Buyers should treat this as a distributor or broker without confirmed processing capacity. All technical data originates from the product listing and industry norms, not from supplier-provided specifications.
