Enhanced hydrosulfite chemistries for optimal performance in pulp and paper

Sodium hydrosulfite is especially effective at brightening wood pulp. Conventional hydrosulfites from BASF offer reliability and results for most pulp and paper mills while enhanced grades such as Adlite® or Blankit® bring tailored performance for recycled paper and TMP processes.

Examples of applications include:

Hydrosulfite / Blankit® / Adlite®

  • Pulp bleaching
  • Brightness enhancer for recycled paper
  • Optimization of thermo-mechanical pulping
