Polyvinyl alcohol, commonly known as PVOH or PVA, is a versatile and widely used polymer with a range of applications across various industries. With its unique properties and compatibility, Selvol Polyvinyl Alcohol has become a key player in the realm of polymers. In this article, we will explore the characteristics, uses, and significance of Selvol PVOH in different sectors.
Understanding Polyvinyl Alcohol (PVOH)
Polyvinyl alcohol is a synthetic polymer derived from the
polymerization of vinyl acetate, followed by hydrolysis. This process
transforms the vinyl acetate into polyvinyl alcohol, a water-soluble polymer
with excellent film-forming and adhesive properties. The degree of hydrolysis
and molecular weight can be adjusted to tailor the characteristics of PVOH for
specific applications.
