  • Applications

    Disodium tetraborate octahydrate is widely used as a buffering agent and builder in household and industrial cleaners, aiding water softening and pH stabilization; as a flux in glass, ceramic glazes, and metalworking (including soldering) to improve melting, wetting, and bonding; as a boron source for agriculture to supply plant micronutrient; as a flame-retardant additive in textiles, paper, wood, and plastics; and as a crosslinking agent for polymer systems (notably borate crosslinking with polyvinyl alcohol) in lab and materials applications.
