The global market for Polyvinyl Alcohol (PVA) continues its robust expansion, driven by increasing demand in construction, textiles, paper, and advanced adhesive formulations. Key trends include a growing emphasis on environmentally friendly solutions, pushing manufacturers towards more sustainable production processes and biodegradable product offerings. Furthermore, the diversification of PVA applications, from specialized coatings to high-performance binders, necessitates a granular understanding of technical specifications and customization capabilities. We delve into the intricacies of Poly(vinyl alcohol) Bp26 pva bp24 Polymer pva 2488 1799 2699 pva chemical polyvinyl alcohol powder price for Adhesive/paint, a critical component in various industrial applications.
Innovations in polymerization and hydrolysis technologies are enabling the production of PVA grades with increasingly precise degrees of polymerization and hydrolysis, leading to tailored solubility, viscosity, and film-forming properties. This precision is crucial for optimizing performance in demanding applications such as high-strength adhesives, advanced concrete additives, and water-soluble packaging. The demand for consistent quality and performance across different production batches remains a paramount concern for B2B procurement specialists and R&D departments.
The production of high-quality Polyvinyl Alcohol, particularly grades like those found in Poly(vinyl alcohol) Bp26 pva bp24 Polymer pva 2488 1799 2699 pva chemical polyvinyl alcohol powder price for Adhesive/paint, is a multi-stage chemical engineering process. This intricate process ensures the desired performance characteristics crucial for industrial applications.
The primary raw material, VAM, is typically synthesized through the reaction of ethylene, acetic acid, and oxygen, or from acetylene and acetic acid. This monomer forms the backbone of the subsequent polymer.
VAM undergoes controlled free-radical polymerization to form Poly(vinyl acetate). This process is critical for achieving the target molecular weight and distribution, which directly influences the final PVA's physical properties.
PVAc is then subjected to a saponification reaction, typically using an alkali catalyst (e.g., sodium hydroxide) in an alcoholic solvent (e.g., methanol). This step hydrolyzes the acetate groups into hydroxyl groups, forming Poly(vinyl alcohol). The degree of hydrolysis (e.g., 88% for 2488, 99% for 2699) is precisely controlled to define solubility and bonding characteristics.
The crude PVA solution is purified, precipitated, and extensively washed to remove residual salts, catalysts, and unreacted components. Subsequent drying processes, often utilizing fluidized bed dryers, reduce moisture content to specified levels, preparing the polymer for the next stage.
The dried PVA polymer is then ground into a fine powder, and precisely sieved to achieve specific particle size distributions. This ensures optimal dissolution rates and homogeneous dispersion in end-use formulations.
Throughout the process, rigorous testing is performed according to international standards (e.g., ISO 9001:2015). This includes evaluating viscosity, degree of hydrolysis, residual acetate, pH, ash content, and heavy metal presence. Only batches meeting strict specifications are packaged, ensuring consistent product quality and reliable performance.
The typical service life of PVA in dry powder form, when stored under proper conditions (cool, dry, sealed container111s), can extend for several years without degradation. For specific applications like adhesives, this extended shelf life ensures product stability and performance over time. Our products adhere to stringent internal and international testing standards, providing superior binding capabilities and excellent film formation, which are crucial in demanding target industries such as construction, textiles, and packaging.
Understanding the precise technical parameters of Poly(vinyl alcohol) Bp26 pva bp24 Polymer pva 2488 1799 2699 pva chemical polyvinyl alcohol powder price for Adhesive/paint is paramount for engineers and formulators. Different grades are distinguished primarily by their degree of hydrolysis and polymerization, which dictate solubility, viscosity in solution, and film characteristics. The numbers in grade designations (e.g., 2488, 1799, 2699) typically refer to the viscosity of a 4% aqueous solution at 20°C and the degree of hydrolysis, respectively.
For example, "PVA 2488" commonly indicates a product with a viscosity of approximately 24 mPa.s (for a 4% aqueous solution at 20°C) and an 88% degree of hydrolysis (partially hydrolyzed). "PVA 1799" would denote a lower viscosity (around 17 mPa.s) but a higher degree of hydrolysis (around 99%, fully hydrolyzed). These distinctions are critical for optimizing performance in specific applications.
| Parameter | PVA Grade 2488 | PVA Grade 1799 | PVA Grade 2699 |
|---|---|---|---|
| Degree of Hydrolysis (mol%) | 87.0 - 89.0 | 98.0 - 99.0 | 98.0 - 99.0 |
| Viscosity (4% aq. solution, 20°C, mPa.s) | 22.0 - 26.0 | 15.0 - 19.0 | 24.0 - 28.0 |
| Volatile Content (%) | ≤ 5.0 | ≤ 5.0 | ≤ 5.0 |
| Ash Content (%) | ≤ 0.5 | ≤ 0.5 | ≤ 0.5 |
| pH (4% aq. solution) | 5.0 - 7.0 | 5.0 - 7.0 | 5.0 - 7.0 |
| Mesh Size (120 mesh pass rate %) | ≥ 99.0 | ≥ 99.0 | ≥ 99.0 |
