Borates—like boric acid powder, boric acid granular, borax pentahydrate, borax decahydrate, and anhydrous borates—are naturally fire resistant. That’s why manufacturers add borates to their cellulose and fiberglass insulation products. Adding boric acid and other borates to insulating materials means their fibers will be flame retardant, making the structures they are used in safer. Rose Mill can provide bulk boric acid in granular or powder form, and provide packaging designed to make your manufacturing process more efficient.
