PVA 2699 is a type of High viscosity and Full hydrolyzed Polyvinyl Alcohol. It’s a water-soluble synthetic polymer derived from the hydrolysis of polyvinyl acetate. It is characterized by its high polymerization degree and high hydrolysis rate, making it suitable for applications requiring excellent film-forming properties, adhesion, and chemical resistance.
Key Features
High Hydrolysis Degree: ≥ 98% hydrolysis, resulting in superior water solubility and stability.
Viscosity: high viscosity range, ensuring strong bonding and cohesive strength.
Film Strength: Forms tough, flexible, and transparent films with good barrier properties.
Thermal Stability: Stable under moderate heat, suitable for high-temperature processing.
Biodegradability: Environmentally friendly, decomposes under microbial action.
Equivalent Grades:
100-70 | CCP BF-26 | Sekisui Selvol 350 – Celanses
