In Today’s era of globalization, when we are focusing on the use of any organic or inorganic chemicals in any of the industrial applications, the first thing that strikes our mind is nothing but safety. Whenever, wherever safety properties are desired, this is our normal human nature to move for a better, low toxic, more biodegradable and less corrosive substitute which will serve the same purpose in a better and safer way.
The use of Ethylene Glycol or Mono Ethylene Glycol or MEG is well known among various industrial applications as Antifreeze agent. But the time has changed. Ethylene Glycol is a bit more toxic than other Heat Transfer Fluids especially other glycols. So, it’s time to change our mind. It’s time to shift from Mono Ethylene Glycol to Propylene Glycol or Mono Propylene Glycol or PG or MPG.
Propylene Glycol is the replacement of Ethylene Glycol in newer automotive antifreezes and de-icers in aircrafts. Like Ethylene Glycol, Propylene Glycol also has the special physical characteristics of depression of freezing point when mixed with water. It happens due to disruption of hydrogen bonding. Pure water freezes at 0OC. But aqueous solution of Propylene Glycol (10% by weight) has a freezing point of -3OC. 30% by weight aqueous solution of Propylene Glycol freezes at -12OC and a 60% by weight Propylene Glycol and water mixture can further lower down this freezing point to -51OC.
The major advantages of Propylene Glycol which force the industries to replace Ethylene Glycol are as follows:
1. Low toxicity
2. Ensures higher safety
3. Readily biodegradable
Chemtex Speciality Limited is one of the leading international ISO 9001:2008 certified companies dedicated to provide its clients Inhibited Propylene Glycol blended with leading edge technologies. Normal Propylene Glycol may corrode the system metals like aluminum, cost iron, copper, brass, solder etc. which are used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters.
But like each and every time Chemtex has a one stop solution for the corrossion problem. You don’t have to think about it twice. You don’t need to add Corrossion Inhibitors to prevent system metal corrossion. Leave it on Chemtex. Our Inhibited Propylene Glycol will draw the finishing line to all these problems and your system will perform like never before.
Inhibited Propylene Glycol is used in chillers, glycol systems, boiler systems, solar panels, and many other water based systems. It is usually produced from either propylene oxide or glycerol.
