Versatile Industrial ApplicationsGH-17R Polyvinyl Alcohol is ideal for use across multiple industries, including adhesives, textiles, paper manufacturing, ceramics, and construction. Its superior water solubility and film-forming abilities make it especially useful in processes requiring high-quality adhesive properties, stable sizing agents, and as a binder in various composites. The product's stability and safety further enhance its viability for commercial production.
Excellent Physical and Chemical PropertiesGH-17R presents as a white, odorless powder or granule with a molecular weight of approximately 89,000-98,000 g/mol. It dissolves easily in water, featuring a neutral pH (5-7 in a 4% solution), and remains chemically stable in storage. With a density of 1.31 g/cm3 and a melting point around 230C (decomposes), it maintains consistent performance in demanding industrial settings.
Safe, Reliable, and Easy to StoreThis polyvinyl alcohol variant is non-flammable and classified as non-hazardous. Proper storage in its original sealed packaging, kept in a cool and dry environment, can extend its usability for up to 24 months from the production date. The innovative multi-layer paper bag design protects the product from moisture and contamination during storage and handling.
