Polyvinyl Alcohol (PVA) PVA2488-01A
ZHUOJUN® PVA products’ dissolvent ability is determined by the degree if alcoholysis and Polymerization. When polymerization increases, the ability to dissolve will reduced. Likewise, when the degree of alcoholysis decreases, the dissolvent teamperature will reduced and water solubility will increase. Fully alcoholysed PVA products are more sensitive to temperatures changes. Such products cannot dissolve or experience partial in properties. When temperature falls below required degree, blending will be difficult to create foam. Should the temperature exceed the required degree for partial alcoholysis products, temperature must be controlled at acceptable range for ease of dissolving.
