Japan Quarry Polyvinyl Alcohol is a solid, powder, cream or white, non-toxic, non-flammable, odorless, taste-soluble, water-soluble material with excellent dielectric strength.
What is Japan Quarry Polyvinyl Alcohol?
Vinol is obtained by partial hydrolysis by polymerization of vinyl acetate monomer. In this process, the ester group is replaced by the hydroxyl group and the process is completed with the presence of sodium hydroxide as the catalyst.
Advantages and features of Japan Quarry Polyvinyl Alcohol
This synthetic polymer with chemical formula C2H4O has a high bonding ability, is chemically neutral, is effective in excellent film formation, has a molecular weight of 44.053 g / mol, is very stable, insoluble in organic solvents, desirable resistance property It is resistant to chemicals, it can dissolve in hot and cold water, it has the ability to emulsify, and when it is heated to decompose thermally, it emits scorching vapors.
Application of Japan Quarry Polyvinyl Alcohol
This material is widely used in various industries due to the advantages and features that we mentioned in the previous sections. For example, in the production of water-resistant adhesives, in agricultural industries to increase soil adhesion, in the textile smoothing stage, in the production of eye drops, in the paper industry, in the food packaging industry, in petroleum solvents , Is used in plastic molding compounds, in the preparation of various coatings, etc.
Terms of use and storage of polyvinyl alcohol
People who are in long-term contact with this substance in warehouses and factories are better to use masks, glasses, gloves, work clothes and hats to prevent getting the disease. It is also recommended to store this dry material, cool and equipped with strong ventilation systems.
