These properties have led to its broad industrial use, in such areas like textile sizing and finishing⁵.

Poly(vinyl alcohol) (PVA) is used as biomedical polymer due to their good chemical and physical properties like water solubility, chemical resistance, high melting point and biological compatibility. In addition, it is an inexpensive, non-Steel Lined PE (PTFE / PP /PO) Pipe for Chemical Factory.
