PVA Polyvinyl Alcohol 080-44(2480)
Overview
PVA 080-44(2480) 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 080-44(2480) 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.
