PVA 2488L(V50) Powder Polyvinyl Alcohol (500g)

PVA 2488L(V50) Powder Polyvinyl Alcohol (500g)
- 1.Formula:(C2H4O)n. Alcoholysis degree:88%,Degree of polymerization:2400,Molecular weight:105600. Solubility: The solubility of PVA varies with the degree of alcoholysis and degree of polymerization.
- 2.Polyvinyl alcohol is a water-soluble polymer obtained by hydrolysis of polyvinyl acetate without polymerization of monomers,White powder.
- 3.Thermal stability: polyvinyl alcohol will soften when heated, and there will be no obvious change below 40 °C. If it is heated for a long time above 160 °C, it will gradually color. When it is above 220 °C, it will decompose and generate water, acetic acid, acetaldehyde and butylene.
- 4.PVA is hardly affected by weak acids, weak bases or organic solvents, and has high oil resistance.PVA is a low-viscosity polymer, and its aqueous solution is very stable at room temperature. The aqueous solution will not deteriorate during storage.
- 5.Film-forming property: Due to the high adhesion between PVA molecules, PVA is easy to form a film, and the formed film is colorless and transparent, with good mechanical strength, smooth surface without stickiness, and good solubility. Molecular film has good light transmittance, high moisture permeability and good printability.
The zip-lock designed package of convenient U-shaped tear,made of high quality materials of PE/PET.
