Core Physicochemical Properties​​​​​​​

There are three key aspects that determine the technological efficiency of our biopolymer. Firstly, the Degree of Deacetylation (DDA) at 95% gives the highest cationic charge density, which leads to the best antibacterial activity and binding capacity.

Second, our controlled molecular weight range allows to balance between biological activity and viscosity. Molecular weight variations with higher molecular weights are excellent in film production and mechanical strength for packaging. Lower ranges increase the cellular penetration for biomedical applications.

Third, the cationic nature solves the biocompatibility problem in industrial applications; Unlike manufactured polymers, this natural derivative degrades to non-toxic residues. Its positive charge electrostatically interacts with negatively charged surfaces and is hence suitable for use in water treatment and wound care formulations.

Industrial & Biomedical Applications

Water Treatment Solutions

Our product is used as a primary flocculent in municipal and industrial waste water treatment plants. It chelates heavy metals (chromium, lead, mercury) and eliminates suspended particles by charge neutralisation. It is superior to aluminium sulphate at higher pHs and decreases the amount of hazardous sludge by 40%. Even better rates of dye removal for textile factories.

Advanced Wound Care & Haemostasis

Our substance is used by medical equipment manufacturers in surgical hemostats and chronic wound dressings. The cationic structure interacts with red blood cell membranes, resulting in fast clotting independent of natural coagulation pathways. This method has been useful in anticoagulated blood, overcoming limits in trauma care.

Biostimulants for Agriculture

The elicitor qualities are applied in crop protection preparations to trigger plant systemic acquired resistance (SAR). Field investigations show a 30-50% reduction in fungal infections with no chemical herbicides. Drought and salinity stress enhance root growth resulting in improved production stability.

Compostable Packaging

Food packaging firms are replacing petroleum based polymers with our Chitosan Powder films. The material provides oxygen barrier qualities similar to synthetic polymers, while providing innate antibacterial protection that increases the shelf life of fresh produce and meat products.

Manufacturing Excellence & Quality Assurance

Bolin has two GMP certified facilities established in 2015 and 2024. Our new factory is equipped with precision automation for closed-loop sustainable extraction methods. Raw materials are screened for pesticides, and suppliers are audited before processing.

Heavy metals testing, microbiological screening and third-party verification are part of a six-stage quality control process. HPLC/UPLC equipment ensures the active ingredient consistency thru the production batches. All materials meet the requirements of the EU Pharmacopoeia for medicinal use.

We have a team of 80 including biochemical engineers and botanists that work on optimising extraction techniques. Our in-house labs perform stability research and application testing to help your formulation development.

Custom OEM Services & Flexible Solutions

We offer end-to-end manufacturing support for completed product firms. Custom deacetylation degrees (70-98%), targeted molecular weights, and particle size optimisation are among our services. We can supply from laboratory volumes of 1kg to industrial barrels of 25kg.

We can accommodate your private label needs with logo design, regulatory documentation and small batch trial production. Our commercial team supports formulation issues and application specific testing techniques.

Sustainable Sourcing & Environmental Commitment

Raw chitin is extracted from our registered 25,800 acres breeding base verified by China Fisheries Bureau Administration. This vertical integration guarantees traceability and removes the environmental impact of wild collecting.

Processing facilities use recirculation systems and energy-efficient extraction processes. The waste shells are composted and used in agriculture. This means zero-waste production cycles. Achieved 2024 carbon-neutral certification thru renewable energy integration.

FAQ

Q: What makes your product different from standard grades?

A: Our 95% deacetylation degree exceeds industry standard 85-90% products, providing higher cationic charge and better performance in antimicrobial and flocculation applications. Molecular weight consistency remains within ±5% across batches.

Q: Can you provide samples for application testing?

A: Yes, free samples (50-100g) are available for qualified industrial customers. Contact our technical team with your specific application requirements for customized testing materials.

Q: What documentation do you provide for regulatory compliance?

A: Each shipment includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and third-party test reports. We maintain ISO22000, HACCP, and cGMP certifications with full audit trail documentation.

Q: How does storage affect product stability?

A: When stored in sealed containers away from moisture and direct sunlight at room temperature, the material maintains specification for 24 months. Humidity exposure causes clumping but doesn't degrade chemical properties.
