Component Specifications

Definition
Moisture content is a key quality parameter in industrial-grade polyvinyl alcohol (PVA) binder powder, representing the mass percentage of water present in the material. It directly affects viscosity, solubility, adhesive strength, and storage stability. Precise control is essential for consistent manufacturing outcomes in applications like adhesives, coatings, and textiles.
Working Principle
Moisture content is determined through loss-on-drying methods, where a sample is heated to evaporate water, and the weight loss is measured. Advanced techniques include Karl Fischer titration for higher accuracy, especially at low moisture levels.
Materials
Industrial-grade polyvinyl alcohol (PVA) binder powder, typically with hydrolysis degrees of 87-99% and viscosity ranges of 4-65 mPa·s (4% aqueous solution at 20°C).
Technical Parameters
