Polyvinyl Alcohol PVA 088-05 With Defoamer
Discription:
Polyvinyl Alcohol, alias PVA, is a water-soluble organic compound, generally white or cream-colored solid. According to the data of Huayuan.com, its chemical structural formula is [C2H4O]n, and the relative molecular weight is 44.053. Soluble in water, slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, petroleum ether, vegetable oil, benzene, toluene, dichloroethane, ethylene glycol, carbon tetrachloride, acetone, ethyl acetate, methanol, etc. various organic solvents. Secondly, polyvinyl alcohol is widely used. At present, as a chemical raw material, it can be used to manufacture polyvinyl acetal, gasoline-resistant pipes and vinylon, paper coating, fabric treatment agent, adhesive, emulsifier, glue, etc.
Polyvinyl alcohol is an organic compound with the chemical formula [C2H4O]n, which is white flake, flocculent or powdery solid in appearance and tasteless. Soluble in water (above 95℃), slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethyl acetate Diols etc. Polyvinyl alcohol is an important chemical raw material used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon, fabric treatments, emulsifiers, paper coatings, adhesives, glues, etc.
Usage:
Polyvinyl Alcohol 1788 has good chemical stability, good insulation and film-forming properties. With the typical chemical properties of polyols, it can carry out reactions such as esterification, etherification and acetalization. In addition, it also has the following performance:
(1) Water-soluble
Storage stability of polyvinyl alcohol 1788 aqueous solution The polyvinyl alcohol aqueous solution has little chemical change when stored for a long time. At room temperature, the viscosity will gradually increase with the extension of the standing time; it will turn into a gel at low temperature, and it will turn into a solution after heating and stirring. If it is placed for a long time, rust inhibitor, preservative, anti-gelling agent and viscosity stabilizer can be added to the solution. However, attention should be paid to the influence of additives on product quality and performance during use.
(2) Film-forming properties
PVA1788 is easy to form film, and its film has excellent mechanical properties. The tensile strength of the film increases with the increase of polymerization degree and alcoholysis degree.
(3) Adhesion
The aqueous solution of polyvinyl alcohol 1788 has good bonding force with hydrophilic cellulose, and the bonding strength increases with the increase of alcoholysis degree and polymerization degree.
(4) Chemical properties of the interface
Polyvinyl alcohol 088-20 (1788) is surface active and reduces the surface tension of water.
(5) Solvent resistance
Polyvinyl Alcohol 088-20 (1788) can be dissolved in polar solution containing hydroxyl group, but it is easy to transform into gel, generally insoluble in non-polar organic solution, and insoluble in inorganic ACID , water is a good solvent.
(6) Thermal stability
Polyvinyl alcohol 088-20 (1788) has good thermal stability and does not change at temperatures below 140 degrees.
