POZH-70 liquid

Liquid POZH-70 is an ethylene glycol aqueous solutions with the addition of anti-corrosion and antifoam additives.

Ethylene glycol is used to obtain mixtures with a low freezing point. Compared to water, ethylene glycol has a lower freezing point and a higher boiling point. It is a part of many liquid substances, including antifreezes, brake and hydraulic mixtures (including POZH-70 liquid), ethylene glycol is widely used in the production of cooling liquids in heating systems, internal combustion engines, in de-icing mixtures in aviation. Liquid POZH-70, thanks to ethylene glycol in its composition, works reliably at low temperatures (down to -70°C).
