Overview of polyvinyl alcohol (PVA)
November 02, 2019

Polyvinyl alcohol (PVA) is a water-soluble high polymer produced by the polymerization and hydrolysis of vinyl acetate (VAC). It exhibits excellent chemical stability and possesses properties such as good insulation, film-forming ability, gas barrier performance, water solubility, adhesion, interfacial chemistry, solvent resistance, and thermal stability.


ElephChem PVA products can be classified based on different degrees of polymerization: low degree of polymerization (DP < 1000), medium degree of polymerization (1000 < DP < 2000), and high degree of polymerization (DP > 2000).


ElephChem PVA products can also be categorized according to different degrees of hydrolysis: low hydrolysis (< 80) ,for example PVA 2088, partial hydrolysis (79-89),such as PVA 2488, PVA 0588, medium hydrolysis (91-98), and complete hydrolysis (98-99).
