Polar WG/me is a long-term frost and corrosion protection concentrate based on monoethylene glycol (MEG). It has been developed for use as a heat transfer medium as well as for technical building equipment, process engineering, geothermal energy, heat pump system businesses and water recooling systems.
Polar WG/me is free of nitrite, nitrate, secondary amine, phosphate, borate and silicone.
