🔍 Product Description

Polyvinyl alcohol (PVA)

Introduction:
Polyvinyl alcohol is a solid that can be white in powder, flake or flocculent form. Glass conversion temperature 60 ~ 85ºC. Polyvinyl alcohol contains many alcohol groups, has polarity, and can form hydrogen bonds with water, so it can dissolve in polar water. Polyvinyl alcohol can also dissolve in hot hydroxy solvents such as glycerol, phenol, etc., insoluble in methanol, benzene, acetone, gasoline and other general organic solvents.

📦 Packing: 25KGS in a kraftbag, each kraftbag has a plastic bag inside.

💡 Usage & Applications:
Polyvinyl alcohol (PVA) is a widely used water-soluble polymer. It can quickly dissolve in water, forming a stable colloid with performance between plastic and rubber.

❓ Frequently Asked Questions

1. What is Polyvinyl Alcohol (PVA) primarily used for?

PVA is a versatile water-soluble polymer used in adhesives, coatings, textile sizing, paper processing, and as a stabilizer in polymer chemical industries.

2. Is PVA soluble in water?

Yes, Polyvinyl alcohol contains many hydroxyl groups and has high polarity, allowing it to dissolve in water and form a stable colloid.

3. What are the storage conditions for PVA powder?

It should be stored in a cool, dry, and well-ventilated area, away from heat sources and moisture, ensuring the bags remain sealed when not in use.

4. What determines the viscosity of Polyvinyl Alcohol?

The viscosity is typically determined by the degree of polymerization and the concentration of the PVA in an aqueous solution, as shown in our technical specification table.

5. In what industries is PVA commonly applied?

It is widely used in construction (as an additive), the textile industry (for fabric strengthening), paper manufacturing, and the food/pharmaceutical sectors for films and packaging.

6. How is the product typically packaged?

Standard packaging consists of 25kg net weight in kraft paper bags with an inner PE plastic bag to protect against moisture.
