APPLICATION:
Polyvinyl alcohol (PVA) is a widely used water-soluble high-molecular polymer, which has extensive applications in industries such as textiles, food, medicine, construction, papermaking, printing, agriculture, steel, and polymer chemicals. Specific applications include:
In the textile industry, it serves as a binder for cellulose fibers and synthetic fibers, enhancing the strength, wear resistance, and softness of the fibers.
In paper production, it is used for paper bonding and coating processes, increasing the mechanical strength, moisture resistance, and smoothness of the paper.
It is widely used as a packaging film in the packaging of food, medicine, and industrial products.
