Application
Suitable for film
PVA 2488 is a white solid, and its appearance can be divided into flocculent, granular and powdery; Soluble in hot water. Its aqueous solution has good adhesiveness and film-forming property;
Film forming performance: PVA 2488 is easy to film forming and has excellent mechanical properties. The tensile strength of the films increased with the increase of polymerization degree and alcoholysis degree.
Adhesion: PVA 2488 has good adhesion with hydrophilic cellulose. Generally, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
Film forming performance: PVA 2488 is easy to film forming and has excellent mechanical properties. The tensile strength of the films increased with the increase of polymerization degree and alcoholysis degree.
Adhesion: PVA 2488 has good adhesion with hydrophilic cellulose. Generally, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
Product advantages
The film made of polyvinyl alcohol 2488 has good transparency, high tensile and crack resistance, good moisture permeability and heat insulation, oil resistance, organic drug resistance, and no static electricity, so it is actually used for textile packaging. It can also be used as food packaging, non-toxic, tasteless, pollution-free, and biodegradable. In addition, it can be compounded with polyethylene, polypropylene, etc., and used as instrument packaging, printing and plate making.
Product characteristics
PVA 2488 is a white solid, and its appearance can be divided into flocculent, granular and powdery; It can be dissolved in water at 80-90 ℃. Its aqueous solution has good adhesiveness and film-forming property;
Film forming property: PVA 2488 is easy to form film, with excellent mechanical properties. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree.
Adhesion: PVA 2488 has good adhesion with hydrophilic cellulose. In general, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.
Thermal stability: When polyvinyl alcohol 2488 is heated to about 100 ℃, its appearance gradually changes. The partially alcoholized PVA began to melt at about 190 ℃ and decomposed at 200 ℃. The completely alcoholized polyvinyl alcohol 2488 began to melt at about 230 ℃ and decomposed at 240 ℃. The pyrolysis experiment showed that the lower the polymerization degree, the faster the weight reduction; The higher the alcoholysis degree, the shorter the decomposition time.
