Pure water freezes at 32°F, but a 60% solution of DOWFROST propylene glycol will push Freezing down to -60°F. …as the temperature continues to drop, the glycol begins to freeze.

How cold is propylene glycol?

In view of this, the application of ethylene glycol and propylene glycol solutions spans the temperature range of -60 to 225°F (-51 to 107°C), depending on the glycol concentration and system type. One feature to look out for when comparing ethylene glycol and propylene glycol is the freezing point properties.

What is the percentage of propylene glycol?

The final product contains 20% Propylene glycol, 1.5% dipropylene glycol and small amounts of other polypropylene glycols. Further purification produces finished technical or USP/JP/EP/BP grade propylene glycol, typically 99.5% or higher.

Is propylene glycol alcohol?

Summary Propylene glycol is a synthetic, colorless, odorless, tasteless liquid belonging to belongs to the same chemical class as alcohol. It should not be confused with the toxic substance ethylene glycol.

Is ethylene glycol an antifreeze?

Can ethylene glycol and propylene glycol be mixed?

Can I mix propylene glycol with ethylene glycol? yes they can be mixed. They do not cause any damage to the cooling system, but slightly impair heat transfer.

What does ethylene glycol do to your body?

When ethylene glycol breaks down in the body, it chemicals that form crystals, and crystals can collect in your kidneys and affect kidney function. Glycol also forms acidic chemicals in the body that alter the body’s acid-base balance, affecting your nervous system, lungs, and heart.

Does Propylene Glycol Prevent Rust?

What is the freezing point of 30 propylene glycol?

The freezing point of 30% propylene glycol is 8°F But the burst point is -18°F. The system will be protected, but the coolant will be muddy. By definition, freezing point is the temperature at which ice crystals begin to form. The liquid will become slushy, but it will not expand.

Does propylene glycol expand when heated?

What is propylene glycol toxicity?

Toxic effects include hyperosmolarity, increased anion gap metabolic acidosis (due to lactic acidosis), acute kidney injury and sepsis-like syndrome. Treatment of toxicity includes hemodialysis to effectively remove propylene glycol. Prevention is best achieved by limiting the dose of propylene glycol infused.

Can bacteria grow in propylene glycol?

Both ethylene and propylene glycol decompose at high temperatures. … at these concentrations, bacteria biodegrade propylene glycol, leading to rapid growth of bacterial contamination.At levels above 1% and below 20%, some bacteria can pass limited growthespecially at moderate temperatures.

Can I mix different brands of propylene glycol?
