Product Description:
Poly(vinyl alcohol) is widely used as a binder in the production of adhesives, coatings, and paper. Its water-soluble nature makes it ideal for creating temporary protective films and release layers in various industrial processes. In the textile industry, it serves as a sizing agent to strengthen yarns during weaving. Additionally, it is a key component in the manufacture of water-soluble packaging films and is used in the formulation of eye drops and contact lens solutions due to its biocompatibility. In construction, it acts as a modifier in cement and mortar to improve workability and adhesion. It is also employed in the production of emulsifiers and stabilizers for polymerization processes.
