Carbamide - ammonia complex

LIQUID CARBON DIOXIDE

GOST 8050-85

Chemical formula CO2

MaiN properties and field of usage

Carbon dioxide is odourless colourless liquid; it is non-toxic and non-explosive.

It is used for creation of shielding medium during metals' welding, in food industry for aerated drink' manufacturing; for cooling, freezing and storage of the foodstuffs; for the casting moulds' drying; for the fire-extinguishing needs.
