description Product Description
Poly(vinyl alcohol) is widely used in the production of adhesives and binders due to its strong film-forming and bonding properties. It is a key component in paper coatings, enhancing strength and smoothness. In the textile industry, it serves as a sizing agent to protect fibers during weaving. This polymer is also essential in the manufacture of water-soluble films, which are used in packaging for detergents and agrochemicals. In the medical field, it is utilized in contact lens solutions and as a component in drug delivery systems. Additionally, it plays a role in the creation of emulsifiers and stabilizers in various industrial processes. It is employed in construction as an additive in cement and mortars to improve adhesion, flexibility, and workability. In cosmetics and personal care products, it functions as a binder, thickener, and film-former owing to its non-toxic nature and compatibility with skin.
