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

Cationic Starch VN6105 from Thuan Phat Hung is a modified starch carrying a formal positive charge across the full pH range, which gives it a strong affinity for negatively charged substrates like cellulose and synthetic fibres. This grade is engineered to enhance retention of fines and sizing chemicals in paper production, improving sheet strength and reducing the amount of sizing agents required. The supplier lists it as suitable for demanding systems where high retention and strength are critical.

The starch is typically derived from cassava or corn, with cationic groups introduced through chemical modification to achieve the desired charge density. Industry standard cationic starches for paper often exhibit a degree of substitution between 0.02 and 0.05, with a typical viscosity of 200 to 500 cP at 5% concentration and 25°C. These properties ensure efficient binding to fibres and fillers, which is essential for improving drainage and formation on the paper machine.

Paper manufacturers use cationic starch primarily in the wet-end process to boost dry strength, retention, and drainage. It is also effective in surface sizing to improve printability and resistance to water penetration. Buyers should confirm suitability for their specific paper grades, as performance can vary with fibre type and machine conditions. The product is supplied as a dry powder, with packaging and handling instructions available from Thuan Phat Hung.
