What is PVA? A Simple Guide to Polyvinyl Alcohol
Polyvinyl Alcohol (PVA) is a synthetic polymer that has become a cornerstone of modern industry. Unlike many plastics, PVA is water-soluble, non-toxic, and biodegradable, making it a favorite for eco-conscious applications. At Shijiazhuang Kehao Chemical Co., Ltd., we specialize in producing high-quality PVA for diverse global needs.
What Exactly is PVA?
PVA is made by breaking down another polymer, polyvinyl acetate (common in glue), into vinyl alcohol units. The result is a versatile material that dissolves in water but remains stable in oils and solvents. Key facts:
- Chemical formula: (C₂H₄O)ₙ
- Appearance: White or cream-colored powder or granules
- Solubility: Dissolves in hot or cold water, depending on grade

Why is PVA So Widely Used? Key Properties
1. Water Solubility
PVA dissolves completely in water, leaving no residue. This makes it ideal for dissolvable packaging (e.g., laundry pods) and temporary adhesives.
2. Film-Forming Ability
PVA creates strong, flexible films used in food packaging, embroidery backing, and pharmaceutical coatings.
3. Biodegradability
Unlike conventional plastics, PVA breaks down naturally in water and soil, reducing environmental harm.
4. Adhesive Strength
PVA’s glue-like properties are harnessed in paper, textiles, and wood adhesives.
Top Applications of PVA Across Industries
🏭 Textiles
- Fiber sizing: Protects yarns during weaving.
- Fabric coatings: Water-resistant yet breathable films.
🧪 Construction
- Cement additives: Improves mortar strength and flexibility.
- Tile adhesives: Enhances bonding power.
💊 Pharmaceuticals
- Drug capsules: Dissolves safely in the body.
- Contact lens lubricants: Provides moisture without irritation.
🍃 Eco-Friendly Products
- Dissolvable packaging: Reduces plastic waste.
- 3D printing filaments: Water-soluble support structures.
Why Choose Shijiazhuang Kehao Chemical Co., Ltd.?
As a leading PVA manufacturer, we guarantee:
- Custom grades: Tailored solubility, viscosity, and particle size.
- Global certifications: ISO 9001, REACH, and FDA-compliant products.
- Technical support: Expert guidance for your application needs.
PVA and Sustainability: A Greener Future
PVA’s biodegradability aligns with global efforts to reduce plastic pollution. When disposed of, PVA breaks into water, CO₂, and biomass within weeks under microbial action—unlike plastics that linger for centuries.
