As an accredited Silicon Tetrachloride factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Silicon Tetrachloride is packaged in a 250 kg galvanized steel drum with a secure, airtight seal and clear hazard labeling. |
| Shipping | Silicon Tetrachloride is shipped in tightly sealed, corrosion-resistant containers, such as steel drums or cylinders, under dry, well-ventilated conditions. It is designated as a hazardous material and must be handled with appropriate labeling, documentation, and precautions to prevent contact with moisture and to comply with international transport regulations. |
| Storage | Silicon Tetrachloride should be stored in tightly sealed, corrosion-resistant containers, such as glass or steel drums, in a cool, dry, and well-ventilated area. Keep it away from moisture, water, and incompatible substances like strong bases. Clearly label containers and ensure proper secondary containment to avoid leaks or spills. Protect from physical damage and store away from heat and direct sunlight. |
