The market for polyvinyl alcohol (PVA) is experiencing dynamic growth, driven by expanding applications across diverse industries. As a water-soluble synthetic polymer, PVA exhibits unique properties such as excellent film-forming capabilities, adhesive strength, and chemical resistance. This versatility positions poly vinyl alcohol cas as a critical component in advanced materials and manufacturing processes. Industry trends indicate a sustained demand for specialized PVA grades, particularly those with tailored hydrolysis degrees and viscosities, to meet the stringent requirements of high-performance applications. The shift towards sustainable and eco-friendly solutions also bolsters the demand for PVA due to its biodegradability under certain conditions.
Key market drivers include the burgeoning packaging industry, which utilizes PVA films for their barrier properties, and the textile sector, where PVA serves as a sizing agent. Furthermore, its role in the construction industry as a binder and in the production of polyvinyl butyral (PVB) for laminated safety glass highlights its broad utility. The technical specifications of poly vinyl alcohol cas, notably its CAS number 9002 89 5, are fundamental identifiers in global chemical trade and regulatory compliance, ensuring product integrity and traceability. Understanding these foundational aspects is crucial for B2B decision-makers seeking reliable and high-quality PVA solutions for their operational needs.
The production of PVA (Polyvinyl Alcohol) Powder, specifically `PVA Manufacture Polyvinyl Alcohol Powder`, involves a sophisticated multi-stage chemical synthesis process. Unlike traditional material processing methods like casting or forging, the manufacturing of this polymer is rooted in polymerization and hydrolysis. The primary raw material is vinyl acetate monomer, which undergoes polymerization to form polyvinyl acetate (PVAc). This initial polymer then undergoes a controlled alkaline or acidic hydrolysis reaction, wherein acetate groups are replaced by hydroxyl groups, converting PVAc into polyvinyl alcohol. The degree of hydrolysis is a critical parameter, directly influencing the final properties of the poly vinyl alcohol cas, such as its water solubility, adhesive strength, and tensile properties.
Following hydrolysis, the resulting PVA solution is processed to obtain the desired `pva powder` form. This typically involves techniques like spray drying or drum drying, followed by grinding and sieving to achieve specific particle size distributions. Throughout this entire process, stringent quality control measures are implemented, adhering to international standards such as ISO 9001 for quality management systems. This ensures the consistency and purity of the final `pva polymer` product, which is essential for its performance in sensitive applications. For instance, in the textile industry, consistent `polyvinyl powder` specifications are vital for uniform sizing, while in the paper industry, controlled viscosity of the PVA solution ensures optimal coating performance. The adherence to such rigorous manufacturing protocols guarantees a reliable product lifecycle and superior performance in diverse industrial settings.
The performance of `polyvinyl powder` is largely dictated by its precise technical specifications. Key parameters include the degree of hydrolysis (mol%), viscosity (mPa.s), molecular weight (Daltons), and volatile content. For instance, a higher degree of hydrolysis (e.g., 98-99%) indicates a fully hydrolyzed PVA, suitable for applications requiring superior water resistance and tensile strength, whereas partially hydrolyzed grades (e.g., 87-89%) offer improved adhesion and redispersibility. The viscosity, often measured as the viscosity of a 4% aqueous solution at 20°C, correlates with the molecular weight and influences the workability and rheology in various formulations.
Parameter | Units | Typical Range (Standard Grades) | Impact on Application |
---|---|---|---|
Degree of Hydrolysis | mol% | 87-89 (Partial), 98-99 (Full) | Solubility, Water Resistance, Adhesion |
Viscosity (4% Solution, 20°C) | mPa.s | 3-60 (Grade Dependent) | Film Formation, Thickening, Binding Properties |
pH (4% Solution) | - | 5.0-7.0 | Solution Stability, Compatibility with other Additives |
Volatile Content | % | ≤5.0 | Product Purity, Storage Stability |
Ash Content | % | ≤0.5 | Purity, End Product Quality |
Particle Size | mesh | 60-120 (Typical for finer powders) | Dissolution Rate, Dispersion Uniformity |
