Introduction
Boric acid is a white powder or transparent shiny scale-like crystal that feels slightly soapy to the touch. It is an extremely weak acid that releases hydrogen ions in aqueous solutions primarily by binding to hydroxide ions from water molecules. Heating to 170°C-300°C causes it to gradually lose water, forming metaboric acid, tetraboric acid, and finally boric anhydride (boron trioxide).

Applications
- Glass & Fiberglass Industry: Used to improve the heat resistance and transparency of glass products, enhance mechanical strength, and shorten melting times.
- Wood Preservation & Insecticide: Possesses mild fungicidal and insecticidal (e.g., against termites and cockroaches) properties.
- Flame Retardant: Combined with borates, it releases water upon heating and forms a glassy coating to isolate oxygen.
Storage Requirements
Store in a dry, clean, well-ventilated warehouse, protected from moisture and rain. Do not store or transport together with alkaline substances.
Handling and Precautions
Presents certain reproductive toxicity risks. Prolonged inhalation or extensive contact with broken skin may cause poisoning. Operators must wear dust masks and gloves to avoid inhaling dust. Strictly forbidden to consume.
Formula
Eco-friendly Cockroach Bait: Boric Acid Powder (40%) + Flour/Sugar/Onion Paste (60%).
Function: Boric acid acts as a stomach poison here. The sweet/savory food attracts cockroaches to eat it. Once in their digestive tract, boric acid destroys the stomach lining, causing the cockroach to dehydrate and die within a few days. Because it is non-volatile, the efficacy is long-lasting.
Packaging
fiber drum or carton box, lined with PE bag. Customized packaging available upon request.
