Polyvinyl alcohol (PVA) is a synthetic polymer that is widely used in various industries due to its unique properties. PVA 088-04 is a specific grade of PVA with its own set of characteristics. Here are some of the features and properties of PVA 088-04:
1. Solubility: PVA 088-04 is highly soluble in water, making it easy to work with in aqueous solutions.
2. Film-forming: It has excellent film-forming properties, allowing it to create thin, transparent, and flexible films when dried.
3. Adhesive properties: PVA 088-04 exhibits good adhesive properties, making it suitable for use as a glue or binder in various applications.
4. Barrier properties: PVA 088-04 has good gas barrier properties, especially against oxygen. This makes it useful for packaging materials where oxygen barrier properties are required.
5. Chemical resistance: PVA 088-04 shows resistance to many chemicals, including acids, alkalis, oils, and organic solvents. However, it is not resistant to strong oxidizing agents.
6. Biodegradability: PVA 088-04 is considered biodegradable under certain conditions, which makes it environmentally friendly compared to some other synthetic polymers.
7. Low toxicity: PVA 088-04 is generally considered non-toxic, making it safe for many applications, including those involving contact with food.
8. Hydrophilicity: PVA 088-04 has a high degree of hydrophilicity, meaning it has a strong affinity for water. This property makes it suitable for applications where water absorption or moisture retention is desired.
9. Mechanical properties: PVA 088-04 exhibits good mechanical strength, flexibility, and elongation properties. These characteristics make it suitable for applications requiring both strength and flexibility.
10. Film transparency: PVA 088-04 produces transparent films, allowing for visual clarity in applications such as coatings and packaging.
