Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical degree of hydrolysis for this PVA powder? **A**: The degree of hydrolysis typically ranges from 88% to 99%, as listed in the product parameters. This value affects solubility and final properties. Always confirm the exact grade with the supplier. ### Q: How should the powder be stored? **A**: Store in a sealed, dry condition at temperatures between 5°C and 35°C. Avoid freezing and high heat. Under these conditions, the shelf life is 12 to 24 months. ### Q: What is the recommended dissolution method? **A**: Dissolve the powder in water with stirring, typically at 20°C. The solubility is at least 90% at this temperature. For faster dissolution, use finer particle sizes or warm water, but follow manufacturer guidelines. ### Q: Are there any standards for verification? **A**: The parameters reference GB/T 12010 for several properties. However, this standard is a reference for testing methods, not a certification. Verify compliance with the manufacturer for your specific application. ## 6.
