Poly(vinyl alcohol) CAS#9002-89-5
1. Eco-Friendly Water Solubility：
Soluble in hot water and biodegradable, PVA replaces plastics in packaging films, agricultural mulch, and dissolvable laundry bags, reducing microplastic pollution.
2. Superior Film-Forming & Adhesion：
High hydroxyl density enables strong hydrogen bonding, creating durable oxygen-barrier films for food packaging and adhesive layers in paper/textile industries.
3. Biocompatibility & Low Toxicity：
High LD50 (>20,000 mg/kg) and non-carcinogenic (IARC Group 3) properties support safe use in pharmaceuticals, contact lenses, and wound dressings.
4. Scalable Industrial Processing：
Available in bulk powder form (1 FCL MOQ) with tunable solubility via molecular weight control, enabling cost-effective extrusion or solution casting for diverse manufacturing.
Polyvinyl alcohol (PVA) is a solid material that may appear as a white powder, flakes, or flocculent particles. Its glass transition temperature ranges between 60–85°C. Due to its numerous hydroxyl groups and polar nature, PVA can form hydrogen bonds with water, making it soluble in polar aqueous solutions. Additionally, it dissolves in hot hydroxyl-containing solvents like glycerol and phenol but remains insoluble in common organic solvents such as methanol, benzene, acetone, and gasoline.
