Antifreeze fluid is obtained through mixture of a base fluid which is Mono Ethylene Glycol as the most familiar one and manufactured by some additives to improving quality and preventing corrosion and rusting beside of using water and paint.

Another advantage of using Ethylene and Propylene Glycol as the base fluid in the antifreeze formulation is their low environmental adverse effects. Ethylene and Propylene Glycol can enter the aquatic environment following consumption. Both solutions are highly soluble and their damaging effects on fish, wild life, plants, and microorganisms are low. The Biochemical disintegration of these two materials occurs rapidly and completely.

Generally, the components of an engine coolant fluid are included of base fluid, anticorrosion agents, anti-frothing agents with water and specific paint. The color would be differed depends on taste and standards of each manufacturer.

An antifreeze product not only prevents freezing of the engine cooling system but also prevents corrosion of engine components. Furthermore, it also wards off the resulting heat and establishes thermal balance in the engine, water thermal capacity and its contents prevent formation of sediments of water minerals inside the engine and the radiator. Hence, unlike the common belief, this liquid must be inside the automobile radiator in all seasons. Some of the most important properties of a standard engine coolant same as Sadra Naft Parsian antifreeze are listed as following:

* High boiling point.

* Suitable and controllable freezing point.

* Low corrosion.

* High heat transfer.

* High chemical stability.

* Mixable with proper water amount.

* Nonflammable and low toxicity.
