Shuangxin PVA 2688A 088-60 For Fiber Yarn
Description:
Shuangxin PVA 2688 Characteristic,
(1) Solubility: hydrophilic, easily soluble in water (generally dissolved in hot water above 90℃), 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 130℃, the appearance gradually changes. Fully hydrolyzed 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, acetal reaction with formaldehyde, acetaldehyde, etc., the product has water resistance.
