Polyvinyl Alcohol (PVA) 1799 – High-Strength, Fully Hydrolyzed Polymer for Industrial Adhesives, Textiles, and Paper
Polyvinyl Alcohol (PVA) 1799 is supplied as a fully hydrolyzed, high-viscosity grade synthetic polymer, renowned for its exceptional film strength, adhesive power, and chemical resistance. As a water-soluble resin with outstanding binding properties, it is extensively utilized across diverse manufacturing sectors, including adhesives, textiles, paper, and construction, where reliable performance and consistency are paramount.
Primary Industrial Applications and Functional Uses
This fully hydrolyzed PVA grade is a critical component in numerous industrial formulations:
-
Adhesive and Binding Applications: It serves as the primary film-forming agent and binder in the manufacturing of wood glues, paper adhesives, packaging gums, and remoistenable adhesives due to its strong bonding characteristics and flexibility.
-
Textile Sizing and Warping: It is widely employed as a sizing agent for yarns in the textile industry, providing temporary strength, abrasion resistance, and smoothness during weaving, which is subsequently washed off.
-
Paper Coating and Surface Sizing: Used in paper coating formulations and as a surface sizing agent to enhance strength, printability, oil and grease resistance, and surface smoothness.
-
Construction and Building Materials: Incorporated into cement and mortar additives, joint compounds, and tile adhesives to improve workability, water retention, adhesion, and flexural strength.
-
Polymerization Aid and Protective Colloid: Acts as a dispersion stabilizer and protective colloid in the emulsion polymerization of vinyl acetate and other monomers.
