As an accredited Isobutylene factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Isobutylene is supplied in a 99.5% pure, 50-liter high-pressure steel cylinder, equipped with safety valve and proper hazard labeling. |
| Shipping | Isobutylene is shipped as a liquefied, pressurized gas in specially designed cylinders or tank cars. It is classified as a flammable gas (UN 1961) and requires secure, leak-proof containers. Proper ventilation, grounding, and clear hazard labeling are essential during transport to prevent fire or explosion risks. |
| Storage | Isobutylene should be stored in tightly closed, properly labeled pressure-resistant containers or cylinders, kept in a cool, well-ventilated area away from heat, ignition sources, and direct sunlight. Storage areas must be equipped with leak detection and fire suppression systems, and containers should be grounded and bonded to prevent static discharge. Segregate from oxidizing agents, acids, and halogens. |
