1. Product Introduction & Main Application
Arnico’s Boric Acid is a white, crystalline inorganic compound with very mild acidic properties, produced from the reaction of borax with mineral acids. This multi-purpose substance serves as a flame retardant, a raw material in the production of heat-resistant glass (e.g., Pyrex), a boron micronutrient fertilizer, and a mild disinfectant, playing essential roles in the glass, agriculture, and pharmaceutical industries.

3. Features & Benefits
-
Guaranteed Boron Source: Supplies boron in oxide form to the glass network, multiplying the thermal and chemical resistance of borosilicate glass several times over.
-
Exceptional Pharma Grade Purity: Free from heavy metals and sulfates, which is critical for use in ophthalmic solutions and hygienic detergents.
-
Effective Flame Retardant in Polymers: Releases water at high temperatures and forms a protective glassy layer on the surface of cellulose and polymers.
-
Controlled Solubility in Agriculture: Provides a gradual release of boron in the soil to prevent plant toxicity and ensure a steady supply of this micronutrient.
4. Industrial Applications
-
Glass & Ceramics Industry: The primary material in the production of Pyrex glass, insulation fiberglass, and ceramic glazes.
-
Agriculture Industry: Production of liquid and powder boron fertilizers to prevent hollow heart and black core in fruits like apples and sugar beets.
-
Pharmaceutical & Cosmetic Industry: The active ingredient in eyewash solutions and mild antiseptic lotions.
-
Wood & Textile Industry: A flame retardant in the production of MDF boards and fireproof fabrics.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance has low acute toxicity to humans but may be damaging to fertility. Avoid ingestion and prolonged skin contact. Obtain the MSDS file from Arnico.
-
Storage Conditions: Store in sealed bags in a dry, cool, and well-ventilated place. It does not easily cake, but high humidity should be avoided.
-
Personal Protective Equipment (PPE): When decanting, the use of a dust mask and gloves is recommended.
6. Quality Assurance & COA
All Arnico Boric Acid shipments are provided with a Certificate of Analysis (COA) guaranteeing the boron percentage based on standard titration, to meet the exact needs of the glass and agricultural industries.
