Solubility: Like other forms of PVA, Poval exhibits excellent water
solubility. This property is fundamental to its use in various
applications where water-based solutions and easy dispersion are
essential.
- Film-Forming
Ability: Poval retains the film-forming ability of traditional PVA.
When dissolved in water, it can be applied as a coating or film, providing
a transparent and flexible layer on various surfaces. This characteristic
is crucial in applications such as packaging and adhesives.
- Adhesive
Properties: The adhesive strength of Poval makes it suitable for use
in formulations for adhesives and binders. Its ability to form strong
bonds contributes to its effectiveness in various bonding applications.
- Biodegradability:
Poval, like other forms of PVA, is known for its biodegradability. This
characteristic aligns with the growing emphasis on environmentally
friendly materials and makes Poval a sustainable choice in certain
applications.
