Polyvinyl alcohol (PVA) is usually a white - to - off - white powder or flake - like solid.
PVA has excellent film - forming properties, and the dried film is strong, flexible, and transparent. It also has good water - solubility, and its solubility in water varies depending on the degree of alcoholysis. In addition, PVA shows good adhesion to many materials and can be used as an adhesive. It has certain chemical resistance, but may undergo degradation or chemical reactions under extreme conditions such as strong acids, strong alkalis, or high temperatures.
PVA is widely used in various industries. In the textile industry, it is used as a warp - sizing agent. In the paper industry, it is used for surface sizing and coating. It is also used in the construction, pharmaceutical, and packaging industries, etc. Due to its good biocompatibility, it has applications in the medical field as well.
