Yellow Dextrin
Yellow Dextrin is a yellow powder derived from high-quality corn or tapioca starch through deep transformation under high-temperature roasting and the action of trace acid catalysts. Compared to native starch, the molecular chains of yellow dextrin are broken and rearranged, endowing it with extremely high water solubility and significant bonding strength. Due to its excellent physical and chemical properties, yellow dextrin is widely applied as a highly efficient and eco-friendly adhesive and modifier across various industrial sectors.
