What is Polyvinyl Alochol PVA?
Polyvinyl Alcohol PVA is a white particle or powder. Soluble in water or only able to swell. Resistant to mineral oils, greases, lubricants and most organic solvents. It is hygroscopic.
Polyvinyl Alcohol PVA can be used in textile paste, Vinnie fiber, paper coating agent, building material, adhesive, PVA film, PVB raw material, food and other fields.
When heated, it does not melt, and dehydrating decomposition occurs at about 150ºC, and the color turns yellow. Pva degrades slowly at 100ºC and rapidly at 200ºC
What is the functions and applications of Polyvinyl Alcohol PVA?
1. PVA Film: PVA is Soluble in water, Polyvinyl alcohol film is a green and environmentally friendly functional material with polyvinyl alcohol as the main body, added with modifiers and other additives, processed by special technology, and can be completely degraded by microorganisms in the soil.
2 Pharmeutical Grade:PVA Polyvinyl Alcohol materials are widely used in the Health care field as its perfect and outstanding properties
3.PVA for Glue:PVA Polyvinyl Alcohol glue thickener can increase the viscosity of liquid glue, making the glue system more stable and having good fluidity, leveling and glossiness
