Import Acetylated Oxidized Starch For Paper — Buy in Bulk from Supplier in Viet Nam

VN- 6405 is a two-stage modified tapioca starch, chemically treated through acetylation and oxidation in alkaline hypochlorite at controlled low temperatures between 21 and 38 degrees Celsius. This dual modification yields a cold-water soluble starch with enhanced film-forming properties, delivering measurable improvements in paper surface strength, smoothness, and stiffness at high burst levels. The granule structure retains sufficient integrity to create uniform coatings while allowing complete gelatinisation during the sizing process.

The oxidation stage introduces carbonyl and carboxyl groups that reduce paste viscosity and increase stability, while acetylation esterifies hydroxyl groups to improve hydrophobicity and reduce retrogradation. Typical acetyl content for paper-grade oxidised starches ranges from 1.5% to 2.5%, with degree of substitution usually between 0.01 and 0.05. The product is compatible with most chemicals encountered in surface sizing formulations, including alum, synthetic sizing agents, and optical brighteners, without phase separation or贫or coagulation.

Paper mills and converters source this starch for surface sizing applications where printability, dust control, and water resistance are critical performance targets. End uses include writing and printing paper, linerboard, and specialty packaging where adhesive surface quality determines downstream processing efficiency. Buyers should confirm minimum order quantities, packaging formats, and current availability directly with Thuan Phat Hung, as these trade terms are not specified in the listing data.

Thuan Phat Hung is headquartered in Tan Binh District, Ho Chi Minh City, Viet Nam, operating from postal code 700000. The supplier holds a 'harbor' trust tier on the platform, which represents a baseline verification level rather than advanced supplier accreditation. The listing provides no information about factory location, production capacity, year of establishment, or number of employees, so any such claims would be speculative.

The response rate is recorded at 0.00% with an average response time of zero hours, indicating no recent buyer engagement data is available through the platform. The product description contains specific technical language about the manufacturing process, suggesting direct production involvement rather than pure trading, but buyers should verify manufacturing credentials independently. No certifications, quality management systems, or export licence details are mentioned in the available profile data.
