Packaging & Availability
- Packaging Type
- Packaging and Transportation
In polyethylene drums (net weight200kg) or iso-tank.
Transportation in cold weather, MAA condensation risk increasing. Condensation is caused by the initial temperature, transport time, external temperature, the capacity of tank insulation and heat loss prevention. In order to reduce these factors’ impacting, recommend to using special temperature control system in transportation, then steam can reduce the risk of products condensation.
- Hazard Class: 8
- UN/NA: UN2531
- Packing Group: III
Storage & Handling
- Shelf Life
6months after manufacturing date. And it can be extended to 12 months if the products are well kept and strictly store in the temperature between 20℃~35℃
- Storage & Handling
If the product is to be placed in long-term storage (over three months), inspect the polymerization inhibitor concentrations for significant declines from initial concentrations as necessary. If happen polymerization and heat up, the container should be transferred quickly to well ventilated wide area and cool down it by large quantity water. In case using bulk tank, the space over liquid level in the tank should be controlled to low level oxidation concentration. This treatment may avoid the tank space going in flammable limits. The other side for avoiding polymerization, the oxidation concentration of tank space needs suitable level. So it will be desirable that the tank space is sealed by the gas that oxidation concentration is about 8%.
Close the container tightly. Store in 20℃~35℃. At that temperature this material is melting state. Don’t store long time at 40℃ or more high temperature. Do not store in locations where the product may be subjected to repeated thaw/freeze cycles. (Especially care at winter or early spring.)
Do not store in the same area with organic peroxides.
If freezing or melting occurring in transportation, please note:
No use strong steam or electric heating system (heating cable, electric hood), or maybe local hot spots caused.
No directly use heat water& steam, mixed by the nozzle or T-tube, with the help of hot ring-disk, upper to melt. Increasing steam pressure or moisture can generate heat immediately. And pay attention the temperature will not higher than40℃when heating.
No withdraw from the partial melting tankers, tanks or reserve tanks. During melting and after melting, materials in the cylindrical containers should be mixed completely. Ensure the inhibitor well-mixing before the removal of any liquids. Mixture need to be processed through circulator, stirrer or decimator, but not by passing bubbles into MAA.
MAA implosion will produce heat and smoke. If implosion caused, using plenty of water to wash immediately and transfer lateral materials, and other staff must evacuate.
MAA is corrosive. Once stain on hands or clothing, give a well water washing and with alkaline soap. Once touch eyes, wash and see the doctor.
