Polyvinyl Alcohol 1799
PVA1799 is a common polyvinyl alcohol (PVA) model, where the number "1799" represents its degree of polymerization and degree of hydrolysis. Specifically:
- "17" represents the degree of polymerization (DP), which is about 1700, indicating the length of the molecular chain.
- "99" represents the degree of hydrolysis (Degree of Hydrolysis), which is about 99%, indicating the content of hydroxyl (-OH) in polyvinyl alcohol.
Main characteristics of PVA1799
Water solubility: easily soluble in water to form a transparent solution.
Film-forming property: has good film-forming properties, and the film is transparent and flexible.
Adhesion: has strong adhesion.
Chemical stability: resistant to solvents and oils, stable chemical properties.
Biodegradability: environmentally friendly and biodegradable.
Application fields
PVA1799 is widely used in many industries:
Adhesives: used to make water-based adhesives.
Textile industry: as a slurry or finishing agent.
Papermaking industry: used as a surface sizing agent or coating.
Construction industry: used as a cement additive to improve construction performance.
Packaging materials: to make degradable films.
Cosmetics: as a thickener or film former.
Summary
PVA1799 is a multifunctional chemical raw material. Due to its excellent water solubility, film-forming properties and adhesion, it is widely used in industrial production and daily life. When using it, the appropriate specifications and processes should be selected according to actual needs.
