Chemical properties

It is flammable.Its vapor and air can form explosive mixture. In case of open flame and high heat, it is easy to cause combustion and release toxic gas. Reacts violently with oxidants, strong acids, strong bases, amines, and bromine. Under the high temperature of the fire, the exothermic heat of polymerization can occur, causing the container to rupture.

Storage matters

Usually goods are added with stabilizers.Store in a cool, ventilated warehouse.Keep away from fire and heat sources.The storage temperature should not higher 26℃.The packaging is required to be sealed and not in contact with the air.It should be stored separately from oxidants, acids, alkalis, and edible chemicals, not mixed storage .It should not be stored in large quantities or stored for a long time. Use explosion-proof lighting and ventilation facilities.Prohibiting using the mechanical equipment and tools that are easy to make sparks.Storage areas should be equipped with emergency release equipment and suitable containment materials. The “five pairs” management system for extremely toxic substances should be strictly implemented.
