As an accredited Propyne factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Propyne is typically supplied in 10-liter steel gas cylinders, clearly labeled with hazard warnings, CAS 74-99-7, and transportation guidelines. |
| Storage | Propyne should be stored in tightly closed, clearly labeled cylinders or containers designed for flammable gases. Keep storage areas cool, dry, and well-ventilated, away from heat sources, open flames, and oxidizing agents. Store upright, secured to prevent tipping. Protect cylinders from physical damage and direct sunlight. Ensure all regulations for hazardous materials and compressed gases are strictly followed. |
| Shipping | Propyne is shipped as a liquefied, flammable gas in high-pressure cylinders or tanks. Containers must meet regulatory standards, be properly labeled with hazard warnings (flammable gas, UN No. 2457), and stored upright in well-ventilated areas away from heat or ignition sources. Handling requires appropriate safety precautions and protective equipment. |
