PVA 2688 is a type of High viscosity and Partially Hydrolyzed Polyvinyl Alcohol. It is a water-soluble synthetic polymer derived from the hydrolysis of polyvinyl acetate. It is characterized by its high molecular weight (degree of polymerization ~2600) and a hydrolysis degree of approximately 88 mole%. Its appearance is typically appears as white or creamy granular/powdered solid.
Solubility: Readily dissolves in water (dependent on temperature and concentration), forming a viscous solution with excellent adhesion, film-forming, and emulsifying properties.
Thermal Stability: Stable under normal conditions but degrades at high temperatures.
Chemical Resistance: Resistant to oils, greases, and organic solvents (varies with hydrolysis degree).
