Achieving Highly Flame Retardant Cellulose
Increasing the pH of your cellulose insulation can increase the fire retardancy of the material when using boric acid as a flame retardant. By increasing the pH, the boric acid is converted into the boron anion which crosslinks with the hydroxyl groups of the cellulose forming a three dimensional crosslinking structure that is more dense
