Polyvinyl alcohol(CAS: 9002-89-5)

Polyvinyl alcohol (PVA), CAS 9002-89-5, is a synthetic polymer derived from vinyl alcohol. Its chemical formula is (C₂H₄O)ₙ, with varying degrees of polymerization. PVA is water-soluble, biodegradable, and exhibits excellent film-forming, adhesive, and emulsifying properties. It is commonly used in textiles, coatings, and adhesives due to its versatility and non-toxic nature. PVA’s characteristics include high tensile strength and resistance to moisture, making it suitable for diverse industrial applications.

Polyvinyl alcohol (PVA), CAS 9002-89-5, is widely used in pharmaceuticals as a binder and film-coating agent. In industry, it serves as a component in adhesives, paints, and paper coatings. The food industry employs PVA as a stabilizer and thickener. It is also utilized in research for biodegradable packaging and drug delivery systems. Additionally, PVA finds applications in textiles, water treatment, and as a binder in inks and dyes, highlighting its broad utility across sectors.

Polyvinyl alcohol (PVA), CAS 9002-89-5, is generally recognized as safe (GRAS) for most applications. It has low toxicity and is non-reactive under normal conditions. However, prolonged skin contact or inhalation of dust may cause mild irritation. Safety standards ensure its use in regulated industries, and proper handling, such as using gloves and ventilation, minimizes risks. PVA complies with OSHA and EPA guidelines for safe handling and disposal.

Polyvinyl alcohol (PVA), CAS 9002-89-5, should be stored in a cool, dry place (15-30°C) away from direct sunlight. Maintain low humidity to prevent clumping and degradation. Store in airtight, moisture-resistant containers to ensure stability and prolong shelf life. Avoid exposure to strong chemicals or heat sources. Proper storage conditions preserve its physical and chemical properties for optimal performance in various applications.
