Product Introduction & Main Application
Arnico supplies a comprehensive range of high-grade Sulfur Compounds, including Granular Sulfur for industrial use, Micronized Sulfur for agricultural fungicide applications, and Bentonite Sulfur for soil amendment. These products serve distinct, critical functions—from raw material for sulfuric acid production and rubber vulcanization to a vital nutrient carrier and pH adjuster in modern, high-efficiency agriculture.

3. Features & Benefits
Granular Sulfur: Dust-free handling with excellent flowability, ideal for bulk blending into NPKS fertilizers and large-scale industrial consumption.
Micronized Sulfur: Extremely fine particle size ensures a high surface area for rapid sublimation, superior leaf adhesion, and maximum biological efficacy as a fungicide and miticide.
Bentonite Sulfur: A controlled-release sulfur fertilizer where bentonite swells upon soil contact, disintegrating the pastille into fine particles for rapid microbial oxidation to plant-available sulfate.
Alkaline Soil Amendment: Bentonite sulfur effectively lowers soil pH, improving the bioavailability of locked-up nutrients like Phosphorus, Iron, and Zinc in calcareous soils.
4. Industrial Applications
Chemical Industry: Feedstock for the production of sulfuric acid, carbon disulfide, and detergents.
Agriculture: Control of powdery mildew and mites in vineyards and orchards (Micronized); reclamation of sodic and alkaline soils (Bentonite).
Fertilizer Production: Manufacturing of Sulfur-Coated Urea (SCU) and NPK+S blends.
Rubber & Tire Industry: A primary vulcanizing agent to cross-link rubber polymers for improved elasticity and strength.
5. Safety & Handling
MSDS (Material Safety Data Sheet): All grades are flammable solids. The full MSDS is available for download on the Arnico website.
Storage Conditions: Store in a cool, dry, well-ventilated area away from open flames, heat, and strong oxidizing agents.
Personal Protective Equipment (PPE): The use of a dust mask, chemical-resistant gloves, and safety goggles is mandatory when handling micronized powder.
6. Quality Assurance & COA
Arnico provides a detailed Certificate of Analysis (COA) for each sulfur compound, specifying purity, ash content, and particle size distribution. This guarantees product consistency for your specific application.
