PVA 088-03 & PVA 0388


PVA 088-03(0388) is a type of polyvinyl alcohol (PVA), which is made by polymerization and alcoholysis of vinyl acetate. It is an odorless, non-toxic, non-polluting, water-soluble resin in the form of a white flake, flocculent, or powder solid. PVA 088-03(0388) can be dissolved in water at higher temperatures (e.g., 80~90°C) and has a variety of special properties such as film-forming, adherence, thermal stability, water-solubility, biocompatibility, and so on. It is currently mainly used in the textile, construction, chemical, and agricultural industries.

PVA 088-03 & PVA 0388
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.
