Our commitment to quality ensures that our clients receive a product that not only meets their immediate operational needs but also contributes to enhanced product performance and process efficiency in the long term. This comprehensive guide delves into the technical aspects, applications, and strategic advantages of integrating our PVA solutions into your industrial processes.

Understanding Polyvinyl Alcohol CAS Number and Its Core Properties

Poly(vinyl alcohol) is identified by its unique chemical abstract service (CAS) number, which is 9002-89-5. This poly vinyl alcohol cas identifier is crucial for global trade and regulatory compliance, ensuring that the precise chemical compound is recognized across different jurisdictions and industries. PVA is a semi-crystalline polymer primarily synthesized from polyvinyl acetate through a process called hydrolysis or saponification. The degree of hydrolysis is a critical parameter that dictates the final properties of the PVA, including its solubility in water, adhesive strength, and film formation capabilities. For instance, fully hydrolyzed PVA exhibits higher tensile strength and water resistance once dry, making it ideal for applications requiring robust film properties, while partially hydrolyzed grades offer enhanced solubility and lower viscosity for specific adhesive formulations.

The physical form of PVA, typically as a white or yellowish powder, allows for easy dispersion and dissolution in water, forming stable solutions that can be applied in various industrial processes. Beyond its excellent binding and emulsifying properties, PVA is recognized for its biocompatibility and biodegradability, making it an increasingly attractive option for sustainable applications. The nuanced control over its molecular weight and degree of hydrolysis during manufacturing enables the production of a wide range of PVA grades, each tailored to specific application requirements, ensuring optimal performance across diverse industrial needs. Our comprehensive product portfolio covers various grades of PVA powder, offering unparalleled flexibility for our B2B clients.

The Manufacturing Process of Poly(vinyl alcohol) Powder

The production of high-quality polyvinyl alcohol cas number 9002-89-5 involves a sophisticated two-step chemical process that begins with the polymerization of vinyl acetate monomer (VAM). This step typically occurs through solution polymerization, where VAM is polymerized in the presence of a solvent, usually methanol, and an initiator. This controlled polymerization yields polyvinyl acetate (PVAc), which is then subjected to the crucial hydrolysis stage. In this second step, the acetate groups of the PVAc polymer are replaced by hydroxyl groups, often by reacting with methanol in the presence of a catalyst, usually an alkali like sodium hydroxide. The degree of hydrolysis, as mentioned, is carefully controlled to produce various grades of PVA, from partially hydrolyzed to fully hydrolyzed.

Following hydrolysis, the resulting Poly(vinyl alcohol) is separated, purified, and then dried to form the characteristic white or yellowish pva powder. Rigorous quality control measures are implemented at every stage of this manufacturing process. Our production adheres to international standards such as ISO 9001 for quality management, ensuring consistency and purity. Key parameters like viscosity, degree of polymerization, residual monomer content, and heavy metal presence are meticulously tested using advanced analytical techniques to guarantee that each batch of Poly(vinyl alcohol) meets stringent specifications. This meticulous approach ensures the product’s suitability for demanding applications in industries like textiles, paper coatings, and construction, where consistency and performance are paramount.

Key Technical Parameters and Grades of PVA Powder

The performance of PVA polymer is primarily defined by several key technical parameters, allowing for customization to specific industrial requirements. The most critical parameters include the degree of hydrolysis (mol%), which affects water solubility and strength, and viscosity (mPa.s), which correlates with molecular weight and solution flow characteristics. Other important specifications involve volatile matter, ash content, and pH. Our Factory price CAS 9002-89-5 Poly(vinyl alcohol) PVA powder is available in various grades, each optimized for different applications. For instance, higher viscosity grades are preferred for strong adhesive formulations, while lower viscosity grades are suitable for sizing agents in textiles due to their penetration properties.

Adherence to these precise specifications ensures that our pva product performs consistently in critical industrial applications. For instance, in construction, the right grade of Poly(vinyl alcohol) can significantly enhance the strength and workability of mortars and concrete. For textile sizing, a specific viscosity range is crucial for optimal yarn protection during weaving. Our technical team works closely with clients to recommend the ideal PVA grade tailored to their unique processing conditions and final product requirements, ensuring optimal performance and cost-effectiveness.

Diverse Applications and Industry Trends

The versatility of poly vinyl alcohol cas 9002-89-5 makes it a preferred material across a broad spectrum of industries. In the textile industry, it is widely used as a sizing agent for yarns, improving their strength and reducing breakage during weaving. In paper manufacturing, PVA enhances paper strength, improves printability, and provides oil and grease resistance. The construction sector utilizes PVA as a binder in mortars and concretes, improving adhesion, flexibility, and anti-cracking properties, particularly in demanding applications requiring exterior waterproof pva characteristics.

Beyond these traditional uses, pva polymer is increasingly adopted in advanced applications. It serves as an emulsifier and dispersant in the emulsion polymerization of vinyl acetate and acrylics. In the medical and pharmaceutical fields, biocompatible grades of PVA are used in drug delivery systems, artificial organs, and contact lenses. The global market for PVA is projected to grow significantly, driven by rising demand from the construction, packaging, and textile industries, especially with a heightened focus on biodegradable and sustainable materials. Our expertise lies in providing specialized grades that align with these evolving market trends, including options for waterproof pva applications.
