AI Overview
PVA0498 is a fully hydrolyzed (98.0–98.8 mol%), low-viscosity polyvinyl alcohol (PVA) powder. It is a light-stable, white, water-soluble, and biodegradable polymer used for high-adhesion applications, including textile warp sizing, paper coating, PVAc emulsion production, PVC suspension polymerization, and as a binder for ceramics and paper.
Key Characteristics & Performance
- Fully Hydrolyzed: Grade 0498 indicates a high degree of hydrolysis, leading to high water resistance, strength, and chemical resistance.
- High Adhesion & Film Formation: Excellent for adhesive, binder, and film-forming applications.
- Solubility: Soluble in hot water (), with resistance to solvents and low humidity sensitivity.
- Physical Properties: White powder, non-toxic, and stable, though it can discolor at temperatures above .
Main Industrial Applications
- Textiles: Warp sizing and finishing agents.
- Paper: Surface sizing and pigment coating.
- Adhesives & Binders: Used in ceramics, magnetic materials, and foundry cores.
- Polymerization: Protective colloid for PVAc emulsions and dispersant for PVC production.
Storage Advice
PVA0498 is hygroscopic and should be stored away from moisture, heat, and direct sunlight, avoiding storage near volatile chemicals to prevent deterioration.
