Import Acetylated Oxidized Starch Vn 6405 — Buy in Bulk from Supplier in Viet Nam

Acetylated Oxidized Starch Vn 6405 is a chemically modified tapioca starch produced through a two-stage process. First, the starch slurry undergoes oxidation in alkaline hypochlorite at 21-38°C, followed by esterification with acetic anhydride under mildly alkaline conditions. The final product is neutralized with hydrochloric acid, thoroughly washed, and dried to yield a starch with enhanced functional properties for industrial applications.

This modified starch is engineered for surface treatment in the paper industry, where it improves paper strength, smoothness, and stiffness. It also enhances printing properties, water resistance, and anti-dusting on the paper surface. The starch exhibits good compatibility with most chemicals used in surface sizing solutions, making it a versatile additive for size press applications. Typical industry grades for such starches include low to medium viscosity ranges, with oxidation levels adjusted for specific end-use requirements.

Paper manufacturers and converters source this starch to improve the performance of coated and uncoated papers. It is particularly valued in high-speed printing and packaging applications where surface integrity and adhesive bonding are critical. Buyers often confirm suitability for their production lines by testing viscosity, pH stability, and compatibility with existing sizing formulations. Trade terms such as packaging type, moisture content, and bulk density are usually specified during procurement.
