Polyvinyl Alcohol (PVA) 088-03 & PVA 0388
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
PVA, categorized as a polyvinyl alcohol (PVA), is produced through an alcoholysis reaction and subsequent polymerization of vinyl acetate. This material manifests as a white, powdery substance, characterized by stability and non-toxicity, and it exhibits remarkable water solubility. When introduced to water at room temperature, it readily dissolves to create a stable colloid.
