Polyvinyl Alcohol (PVA) BP 20
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
"Polyvinyl Alcohol (PVA) CCP PVA BP 20 is produced through ultra-high polymerization of vinyl acetate followed by precisely controlled high-degree alcoholysis. This white, uniform granular material is non-toxic, extremely stable, and exhibits good water solubility—readily dissolving in warm water (70-95℃) to form an ultra-high-viscosity stable colloid. With a strictly controlled degree of alcoholysis (87.0%~89.0% or 98.0%~99.0%) and ultra-high viscosity, it is particularly suitable for ultra-high-performance water-based industrial coatings, high-end textile precision sizing agents, super high-strength paper composite bonding, and heavy-duty structural architectural adhesive applications."

Packing & Storage
| Packing | Packaged in 20kg/25kg moisture-proof paper-plastic composite bags lined with PE film, supporting bulk customization. The packaging label includes key information such as model subtype (2088/2099), high-purity grade, net weight and production date. |
|---|---|
| Storage | Store in a dry, well-ventilated and cool place with relative humidity ≤60%, stacked more than 15cm above the ground. Strictly avoid moisture, direct sunlight and contact with strong oxidants or acidic substances. The shelf life is ≥2 years for unopened original packaging; Type 2099 requires enhanced moisture-proof packaging and sealed storage due to ultra-high alcoholysis degree. |

Frequently Asked Questions
What is Polyvinyl alcohol?
Polyvinyl alcohol (PVA) is a synthetic polymer that is soluble in water. It is produced by the polymerization of vinyl acetate and subsequent hydrolysis of the polymer. The hydrolysis process converts the acetate groups into alcohol groups, resulting in a polymeric chain with repeating alcohol units.
PVA is known for its excellent film-forming and adhesive properties. It is often used as a component in adhesives, coatings, and films. PVA films are transparent and have a high tensile strength, making them useful for various applications. PVA is also biodegradable, which adds to its appeal in environmentally friendly applications. One of the notable characteristics of PVA is its water solubility. When in contact with water, PVA dissolves, forming a viscous solution. This property makes PVA widely used in applications such as textile sizing, paper coatings, and as a component in detergents and personal care products.
In addition to its solubility, PVA exhibits good chemical resistance, making it suitable for use in coatings and barriers. It is also resistant to oils, greases, and organic solvents. These properties make PVA versatile and applicable in various industries, including packaging, textiles, paper, construction, and pharmaceuticals.
Furthermore, PVA can be crosslinked with certain agents to enhance its properties further. Crosslinked PVA exhibits improved mechanical strength, thermal stability, and water resistance, making it useful in applications such as membranes, gels, and drug delivery systems.
Overall, polyvinyl alcohol is a versatile polymer with a wide range of applications due to its film-forming, adhesive, solubility, and chemical resistance properties.
