PVA 1799S

PVA 1799S is a type of polyvinyl alcohol (PVA) polymer powder, PVA 1799 Powder CAS 9002-89-5, characterized by its degree of polymerization (DP) of approximately 1700 and a hydrolysis (alcoholysis) degree of 99%. This water-soluble synthetic polymer is widely used in industrial and chemical applications due to its excellent film-forming, adhesive, and emulsifying properties.

Key Properties:

High solubility in water (at elevated temperatures).
Forms flexible, transparent films with good mechanical strength.
Resistant to oils, greases, and organic solvents.
Biodegradable and non-toxic under standard conditions.
