This the simultaneous polymerization of ethene and propylene.
Propylene glycol is generally considered safer than ethylene glycol for use in coolant/antifreeze due to its lower toxicity. This makes propylene glycol a preferred choice for applications where accidental ingestion may occur, such as in RVs or marine engines. Additionally, propylene glycol is less harmful to the environment compared to ethylene glycol.
Ethane and propane are cracked into ethylene and propylene through a process called steam cracking. In this process, the hydrocarbons are heated to high temperatures in the presence of steam, causing them to break down into smaller molecules like ethylene and propylene. These smaller molecules are then separated and collected for further processing.
Would you brush your teeth with anti-freeze from your car's radiator? Absolutely NO, WHY include this ingredient in toothpaste if it is considered harmful?? You are confusing PROPYLENE Glycol with ETHYLENE Glycol. Propylene glycol is not toxic. Ethylene glycol is the substance in engine coolant which will damage internal organs, especially the kidneys. Check out the MSDS for both substances for further information.
Gasline antifreeze is usually just isopropyl alcohol. Many drugstores sell 97-percent isopropanol, and if you put six ounces of it in a 20-gallon gas tank it will do the same thing as Heet (or whatever brand you like) for less money.
The two classes of petrochemicals are, olefins, which include ethylene and propylene; and aromatics, which include benzene, toluene, and xylene isomers.
Polymers derived from polypropylene include polyethylene-propylene (EP) copolymers, ethylene propylene diene monomer (EPDM), and syndiotactic polypropylene (sPP). These polymers have various applications ranging from automotive parts to waterproofing materials.

Ethylene-Propylene-Diene-Monomer.
Mostly ethylene or propylene glycol.
all i know is that the main ingredient is ethylene glycol
Yes, Ethylene glycol and Propylene glycol are very similar chemically, therefore, can be mixed without any bad consequences for the engine.

Usually just ethylene or propylene glycol.
One way to differentiate between ethylene glycol and propylene glycol is by conducting a simple solubility test. Ethylene glycol is completely soluble in water, while propylene glycol is only partially soluble. Additionally, you can use techniques like gas chromatography or mass spectrometry for a more accurate identification.
