China Chitosan manufacturers and suppliers

Chitosan

Industrial grade chitosan is generally produced from offshore shrimp shells and crab shells.Insoluble in water, soluble in dilute acid.

Industrial grade chitosan can be divided into: high-quality industrial grade and general industrial grade. Different types of industrial grade products will have great differences in quality and price.

Our company can also produce classified indicators according to different uses. Users can choose products by themselves, or recommend products by our company to ensure that the products achieve the expected use effect.
