Product Characteristics

• Good water solubility: easily soluble in water, insoluble in almost all organic solvents, can form a stable solution in water, convenient to use in different processes.
• Excellent film-forming property: aqueous solution is easy to form a film, and the film formed has excellent physical properties such as tensile strength and abrasion strength, which can be used to prepare films with good mechanical properties.
• Strong resistance to chemicals and oils: strong resistance to weak acids and alkalis, and excellent resistance to oils and fats, which keeps the performance stable in contact with related substances.
• Excellent barrier properties: able to prevent the penetration of oxygen, water vapor and harmful substances, and can be used in applications where barrier properties are required, such as in the packaging field.
• Biodegradability: Compared with traditional plastic materials, it has biodegradable characteristics, and can be naturally degraded under environmental conditions without producing harmful pollutants, which is in line with the requirements of environmental protection.

Product Applications

• Medical field: Because of its good water absorption, water retention, biocompatibility and non-toxicity, it can be used to make medical dressings to absorb wound exudate, keep wounds dry and help wound healing.
