Packaging, transportation and storage:
Styrene shall be loaded into a dry, clean special tank wagon or galvanized steel drum with appropriate amount of antipolymerization agent (p-tert-butylo-phenol). The net weight of styrene in barrel is 160kg. The barrel mouth should be closed to prevent the infiltration of styrene and water. This product should be stored under 25 ℃ or refrigerated warehouse, in order to prevent the aggregation metamorphism. During transportation, rain and sun exposure should be prevented.
