Product Description:
Poly(vinyl alcohol) is widely used in the production of adhesives and binders due to its strong adhesive properties and ability to form films. It is a key component in paper coatings, enhancing strength and ink receptivity. In the textile industry, it serves as a sizing agent to improve yarn strength and reduce breakage during weaving. Additionally, it is utilized in the manufacture of water-soluble films, which are essential in packaging for single-use detergents and agrochemicals. In the medical field, it is employed in contact lens solutions and as a lubricant in eye drops. Its biocompatibility also makes it suitable for use in drug delivery systems and wound care products. Furthermore, it is a critical ingredient in the production of poly(vinyl butyral), which is used in safety glass interlayers for automotive and architectural applications.
