Appearance: white powder.
Physical and Chemical Data:
Solubility: soluble in hot water.
Characteristics:
PVA is a very widely used water-soluble polymer, it's performance is between plastic and rubber, which can be divided into two big application - fiber and non-fiber.
Main indexes:
It's used as warp sizing agent, emulsifying stabilizer, wet glue agent, water soluble film, etc.
1. Textile
2. Coating
3. Bond
4. Emulsifier and etc.
We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (drums are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
