3.Dissolving Temperature, thickness and time

PVA products dissolvent ability is determined by the degree of alcoholysis and polymerization. When polymerization increased, the ability to dissolve will reduced. Likewise, when the degree of alcoholysis decreased, the dissolvent temperature will reduced and water solubility will increase. Fully alcoholysed PVA products are more sensitive to temperatures changes. Such products cannot dissolve or experience partial swell in properties when temperature falls below required degree. Blending will be difficult and foam created should the temperature exceed the required degree for partial alcoholysis products. Temperature must be controlled at acceptable range for ease of dissolving.
