Polyvinyl Alcohol 2699 Product Description
Polyvinyl Alcohol (PVA) 2699 is a high-performance water-soluble synthetic polymer that is widely used in various industrial applications. It is characterized by its excellent film-forming properties, high tensile strength, and resistance to oils and solvents. PVA 2699 is produced through the hydrolysis of polyvinyl acetate, resulting in a product that is non-toxic, biodegradable, and environmentally friendly. This polymer is available in various grades, with 2699 being one of the most versatile, suitable for a range of applications from adhesives to coatings.
Key Features:
- Water Solubility: PVA 2699 dissolves easily in water, making it ideal for applications requiring a water-soluble binder.
- Film-Forming Ability: It forms a clear, flexible film that is resistant to grease and oils.
- Biodegradable: As a natural polymer, it is environmentally friendly and can decompose under the right conditions.
- Non-Toxic: Safe for use in food packaging and other applications where human contact is a concern.
Common Uses:
- Adhesives: Used as a bonding agent in woodworking, paper, and textile industries.
- Coatings: Employed in the formulation of protective coatings for various surfaces.
