AI Overview
Polyvinyl Alcohol (PVA) 1098 is a high-viscosity, fully hydrolyzed (approx. 98–99% mol) grade of polyvinyl alcohol, known for its strong film-forming, emulsifying, and adhesive properties. It is a white or light-stable, water-soluble powder used heavily in specialized coatings, textile sizing, adhesives, and polyvinyl butyral (PVB) production.
Key Properties and Characteristics:
- Hydrolysis: Fully hydrolyzed ().
- Viscosity: Typically high viscosity.
- Appearance: White to light-yellowish powder.
- Solubility: Excellent solubility in water (fast dissolving), stable in weak acids/alkalis.
- Performance: Strong adhesion, high tensile strength, and excellent chemical resistance.
Primary Applications:
- Adhesives: High-performance adhesives and binders for paper and textiles.
- Coatings: Used in paper coating, surface sizing, and specialized industrial coatings.
- Textiles: Sizing agent and fabric finishing agent.
- Chemical/Industrial: Used as a polyvinyl formal (PVF/PVB) resin raw material, emulsifier, and in construction materials.
- Specialty: Suitable for biodegradable packaging films.
Safety and Handling:
- PVA 1098 is generally considered safe and biodegradable under normal wastewater treatment conditions.
- It is not meant for direct ingestion and should be handled as a chemical raw material, adhering to standard industrial hygiene practices (avoiding dust inhalation, protecting eyes).
