Ethylene or propylene glycol, to depress the freeze point of the fluid. For ethylene glycol, the mixing ratios are typically 30/70 and 35/65, whereas the propylene glycol mixing ratios are typically 35/65 and 40/60. People will commonly mistake Propylene glycol for Ethylene glycol, but the contrast is that Ethylene glycol is toxic. Ethylene glycol adalah cairan yang tidak berbau, tidak berwarna, berasa manis dan seperti sirup. Propylene Glycol. Ethylene vs. Propylene Glycol. Then I noticed the sticker on the machine … Propylene glycol and glycerin often appear the same since they are colourless, odourless, sweet and syrupy. Having a low viscosity means it's transport properties outperform propylene glycol at lower temperatures. We’ve broken down the two to help you make the best choice for placing your glycol order. Propylene glycol has a very low toxicity, which is why it is also found in cosmetics and personal care products, whereas ethylene glycol is poisonous and must be handled with caution to restrict any human or animal exposure. Glycol ether solvents are based on alkyl ethers of ethylene glycol or propylene glycol and have been used for industrial applications for decades. Its physical properties are quite similar to those of ethylene glycol. The difference between ethylene glycol and diethylene glycol is that an ethylene glycol molecule is an individual molecule whereas diethylene glycol molecule is formed by the combination of two ethylene glycol molecules via an ether bond. Some countries require the addition of a bittering agent to make antifreeze unpalatable to animals. It's normally ethylene glycol, but propylene glycol can also be used. Propylene glycol is used to make non-toxic, and environmentally friendly antifreeze but often leads to confusion with its cousin ethylene glycol. The primary difference between propylene glycols and ethylene glycols is toxicity and heat transfer characteristics.
