We supply PVA1788, PVA0588, PVA1799 can replace PVA217, PVA205, AND PVA117. The feature of the products:1.high tensile strength and flexibility, 2.high oxygen and aroma barrier properties3.elongation and tear strength
Property
1, Solubility: soluble in water at room temperature, quick solubility, high alcohol.
2, Membrane made:The solution is easy to form the film, the film is superior tensile strength and abrasion resistance.
3, Viscosity of aqueous solution: Viscosity of aqueous solution Degree is due to the temperature of polymerization change. Lower than other water-soluble polymer.
4, Contains its own sales foam, has the advantage of less blistering, lower cost.
