description Product Description
Poly(vinyl alcohol) is widely used in the production of adhesives and binders due to its excellent film-forming and adhesive properties. It is a key component in water-based adhesives, making it suitable for paper, textiles, and wood applications. In the textile industry, it serves as a sizing agent to strengthen yarns during weaving.
In the medical field, it is utilized in the manufacture of contact lenses, surgical sponges, and drug delivery systems because of its biocompatibility and ability to form hydrogels. It is also used in eye drops and artificial tear solutions to provide lubrication and moisture.
In packaging, poly(vinyl alcohol) is employed to create biodegradable films and coatings, offering an eco-friendly alternative to traditional plastics. It is also used as a barrier layer in food packaging to protect against oxygen and grease.
Additionally, it plays a role in the construction industry as an additive in cement and mortar to improve workability and adhesion. Its water-soluble nature makes it valuable in 3D printing as a support material that can be easily dissolved after printing.
In the paper industry, it enhances the strength and surface properties of paper products. Its versatility and environmentally friendly characteristics make it a valuable material across various industries.
