Politren E-221 is a water emulsion used as a cooling lubricant for press tools used in hot metal forging, in particular in the process of hot metal forging of copper alloys by the Autoforge method. Also used for hot forging of non-ferrous metals. The Politren E-221-based emulsions have an increased service life, high emulsion stability, low foaming, and increased anti-wear and anti-corrosion properties.

Politren E-221 is supplied as a concentrate and must be diluted with water before use.

When diluting, it is sufficient to use a conventional stirrer and stir the product for 10÷30 minutes.

Safety Requirements, Toxicological Properties and Environmental Protection

Politren E-221 concentrate is a nonflammable liquid, which following evaporation of water turns into a flammable liquid with a flash point of not less than 1400C in an open cup.
In terms of toxicological properties Politren E-221 is classified as a low-hazard substance (lowest Class IV hazard as per GOST 12.1.007-76).

When using Politren E-221 the main components polluting the air of the working area are: mineral oil aerosol (maximum permissible concentration (MPC) is 5 mg/m3), triethanolamine aerosol (MPC is 5 mg/m3), graphite aerosol (MPC – 4 mg/m3) and ammonia impurities (MPC – 20 mg/m3).
The premises where Politren E-221 is used shall be equipped with continuously operating supply and exhaust mechanical ventilation.

Within the production facilities the air shall be monitored subject to the shop-floor air monitoring schedule agreed with the local public health authorities.
The personnel involved in handling Politren E-221 coolant lubricant shall wear protective clothing and use personal protective equipment in accordance with standard industry norms.

When manufacturing and/or using Politren E-221 cooling lubricant emulsions, the requirements of "Sanitary rules for working with cooling lubricants and tool lubrication", No. 3935-85 dated 09.29.1985, shall be complied with.
Use a clean soft cloth to remove Politren E-221 from hands or face; rinse the remaining product away with plenty of water or wash away with warm water.
In case of ingress of the cooling lubricant onto working parts of the machinery, the floor of the machinery area shall be cleaned with rags, and the remaining product shall be washed away with water.

For the disposal of waste coolant lubricant, maximum permissible norms for the most toxic component should be referred to. The Politren E-221 maximum allowable concentration in water bodies (MACw), determined for the most toxic water-insoluble component - oil - is 0.4 mg/l; for the most toxic water-soluble component - triethanolamine - is 1.4 mg/l; Politren E-221 maximum concentration determined for triethanolamine supplied for bio-treatment (MCB) is 5 mg/l.
