Product Short Description: POLYVINYL ALCOHOL
Product Technical Specification:
Specifications
Hydrolysis degree: 86.5%–89.0%
Purity: ≥93.5%
Viscosity: 45.0–58.0 mPa·s
Volatile: ≤5.0%
pH: 5–7
Ash: ≤0.5%
Solubility: Stable in almost all organic solvents. Not dissolved in plant oils and grease.
Remarks:
Storage
The material is very stable with no risk of molding and deteriorating. Under dry conditions, it remains stable indefinitely when protected from moisture.
Dissolving Method
Pour a certain amount of water into the dissolving tank. The water temperature should be below 30°C, then start the blender and pour PVA slowly. The filling speed with PVA should be kept to 10 kilograms per minute; this is advisable.
Confirm that the PVA has fully dispersed (about 10-20 minutes), then heat the solution, and it can be completely dissolved when the temperature reaches 90°C, about 1 hour.
Method of Analysis
Viscosity is measured in a 4% aqueous solution at 20°C using a Brookfield-type viscometer.
pH is measured in a 4% aqueous solution at 20°C.
Ash is expressed as Na₂O.
