PVA 1799 is a water-soluble synthetic polymer that is heavily used in the manufacturing of several industrial products. It is a type of polyvinyl alcohol that has a high degree of hydrolysis (87-91%). Polyvinyl alcohol is a versatile polymer that offers excellent chemical resistance, thermal stability, film-forming properties, and dispersion, making it an ideal compound for many industrial applications.

Properties of PVA 1799

Polyvinyl alcohol unites specific properties, such as excellent adhesion, electrical insulation, low volatilization, and high resistance to hydrolysis, with low toxicity, biodegradability, and non-inflammatory characteristics. However, the properties of PVA 1799 differ from other grades of PVA that are commercially available. Some of the key properties of PVA 1799 are:

- High viscosity even in dilute or low concentration
- Excellent water solubility
- High film-forming ability.
- Good alkali resistance
- Good gas barrier properties
- Excellent tensile properties when dried, such as flexibility and strength.

Applications of PVA 1799

PVA 1799 is used in a variety of applications, including textiles, paper finishing, coatings, adhesives, and packaging.

1. Textiles: PVA 1799 is a crucial component in the sizing, finishing, and dyeing of textiles. It provides excellent adhesive properties, improves tensile strength, and prevents abrasion and static build-up in high-temperature conditions.

2. Paper Finishing: PVA 1799 is used in the coating of paper and paperboard to improve their wetting and printing properties. PVA 1799 also enhances the paper's brightness, opacity, and smoothness.

3. Coatings: PVA 1799 enhances the wetting properties of coatings, making them more stable and durable. It increases the adhesion to the substrate and the ability to resist cracking or peeling.

4. Adhesives: PVA 1799 is a key component of water-based adhesive formulations. It provides excellent bonding and adhesive properties, making it an ideal choice for woodworking, laminating, and packaging applications.

5. Packaging: PVA 1799 is used for the manufacturing of packaging films and wraps that have high barrier properties to moisture, gases, and odors. It provides excellent strength and puncture resistance, making it ideal for packaging a wide range of products, from food to industrial chemicals.

In conclusion, PVA 1799 is a versatile and widely used chemical compound that provides excellent properties and is used in various industries. Its high viscosity and excellent water solubility make it an ideal choice for many applications, ranging from textiles to packaging. Its excellent properties offer excellent adhesion and film-forming properties that provide high strength and durability. Therefore, PVA 1799 remains a vital component in many industrial applications, and its importance is only set to grow in the future.
