As an accredited Sulfur Tetrafluoride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Sulfur Tetrafluoride is packaged in a 50-liter high-pressure steel cylinder, labeled with warning symbols and chemical identification details. |
| Shipping | Sulfur tetrafluoride (SF₄) is shipped as a compressed, toxic, and corrosive gas in high-pressure steel cylinders. It must be clearly labeled with hazard warnings and handled according to regulatory guidelines for toxic gases. Storage and transport require well-ventilated areas, away from moisture, and compliant with local and international shipping regulations. |
| Storage | Sulfur tetrafluoride (SF₄) should be stored in tightly sealed, corrosion-resistant steel cylinders or containers, kept in a well-ventilated, cool, and dry area away from moisture, acids, and incompatible substances. Proper temperature control and secure upright storage minimize leakage risks, and containers must be clearly labeled. Access should be restricted to trained personnel due to SF₄'s toxicity and reactivity with water. |
