| (1) Solubility: hydrophilic, easily soluble in water (generally dissolved in hot water above 90ºC), insoluble in almost all organic solvents. (2) Film formation: easy to form film, the mechanical properties of the film is excellent. In addition to H2O, PVA film has excellent resistance to H2, N2, O2 and other gases. (3) Adhesion: good adhesion with hydrophilic cellulose, paper, etc. (4) Thermal stability: when the 17-99 flake is heated to more than 130ºC, the appearance gradually changes. Fully hydrolysed PVA begins to melt at about 230 ° C and decompose above 200 ° C. (5) Solvent resistance: PVA has strong resistance to weak acid and weak alkali, and has good oil resistance. (6) Reactivity: with excellent cross-linking reactivity, can cross-link with boric acid, reaction with formaldehyde,dehyde, etc., the product has water resistance |
| Used in the manufacture of polyvinyl gasoline-resistant pipes and vinylon synthetic fibers, fabric treating agents, emulsifiers, paper coatings, adhesives, etc. |
