Application Guidelines
Recommended Dosage
When used as a reinforcing, rheology-modifying, or film-forming component, an initial loading of 0.1–2 wt%, based on the dry weight of BC, is recommended for screening.
Addition Method
Stir the BC dispersion thoroughly to ensure uniformity, then gradually incorporate it into the aqueous polymer, gel, coating, or composite system.
Dispersion Method
Mechanical stirring is generally sufficient. High-speed shear mixing or homogenization may be used when finer dispersion is required.
Precautions
The addition level should be calculated based on the dry weight of BC, rather than directly on the total weight of the BC dispersion.
Small-Scale Trial Recommendations
Evaluate different addition levels on a dry-weight basis and compare viscosity, water retention, reinforcement, system stability, and film-forming performance.
Packaging and Transportation
Available in gram-scale samples, kilogram-scale trial quantities, and bulk orders of one metric ton or more, meeting procurement needs at different stages, including research and testing, pilot-scale validation, and industrial-scale applications.
Samples are supplied in sealed packaging and are preferably shipped via international express delivery. Please contact our customer service team for an international shipping quotation when placing an order.
For kilogram-scale and larger quantities, packaging options such as drums, large drums, or IBC totes are selected according to the product form and order volume, with an appropriate logistics and transportation method arranged accordingly.
FAQ
Q: What is the difference between bacterial cellulose (BC) and plant-derived CNF?
A: BC is produced through microbial fermentation and does not undergo the lignin and hemicellulose separation processes associated with plant cell walls. Its source, purity characteristics, and native fibrous network structure therefore differ from those of plant-derived CNF.
Q: How should the fiber dimensions of a BC dispersion be characterized?
A: TEM or AFM can be used to observe the dimensions and morphology of the nanofibers, while SEM primarily provides information on the dry-state network structure. During sample preparation, the effects of concentration and fiber aggregation should be minimized to reduce potential errors in dimensional analysis.
Q: Can a BC dispersion be directly incorporated into aqueous formulations?
A: BC dispersions can generally be pre-mixed into most aqueous systems. However, gradual addition is still recommended depending on the viscosity and compatibility of the formulation. High-speed shear mixing or homogenization can be used when finer dispersion is required.
Q: Should the addition level of a BC dispersion be calculated based on wet weight or dry weight?
A: It is recommended to calculate the addition level based on the dry weight of BC. When dispersions with different solids contents are compared directly based on liquid weight, the actual amount of active BC incorporated will differ.
