Materials Encyclopedia | Polyvinyl Alcohol (PVA): Properties, Applications, and Storage

Polyvinyl alcohol (PVA) is produced through the polymerization of vinyl acetate followed by alcoholysis. It is a white, stable, non-toxic, water-soluble polymer, existing as a powdery, flaky, or flocculent solid.

Introduction to Polyvinyl Alcohol Production Processes and Applications

Introduction to Polyvinyl Alcohol Production Processes and Applications

Polyvinyl alcohol (PVA) is a water‑soluble polymer with the chemical formula [C2H4O]n. It appears as a white, flaky, fibrous, or powdery solid and is odorless. It is characterized by its excellent compactness and high degree of crystallinity, strong adhesive properties, and the ability to produce films that are flexible, smooth, oil‑resistant, solvent‑resistant, abrasion‑resistant, and highly gas‑barrier. Moreover, after special treatment, it exhibits outstanding water resistance, making it suitable for a wide range of applications.

The outbreak of conflict in the Middle East has triggered a “price surge” in the chemical industry! Ethylene oxide and polyvinyl alcohol have seen dramatic price increases, accelerating cost pass‑through throughout the industry chain.

The outbreak of conflict in the Middle East has triggered a “price surge” in the chemical industry! Ethylene oxide and polyvinyl alcohol have seen dramatic price increases, accelerating cost pass‑through throughout the industry chain.

As the flames of conflict continue to rage in the Strait of Hormuz and international oil prices surge to nearly $120 within just a few days, cost transmission throughout the global chemical industry chain is spreading downstream at an unprecedented pace. According to the latest data as of March 10, prices for core chemical products such as ethylene oxide and polyvinyl alcohol (PVA) have risen sharply—among them, PVA quotations in the East China region saw a single-day increase of as much as 18.22%, marking the largest daily gain in recent years. From upstream basic raw materials to end‑use disposable gloves, a “price hike storm” triggered by geopolitical conflicts is sweeping across the entire chemical industry.
