Propylene Glycol
Propylene Glycol
(OP)
I am working on a thermal project [experimental] in which 100% [PG] will be used as my transfer fluid and I am having trouble sourcing valid thermal properties at various temps.
The application of this unit will cover a very broad temp. range [233K to 373K].
I was hoping someone could help to point me in the right direction.
Thanks

RE: Propylene Glycol
Dow chemical makes quite a few varieties of both propylene and ethylene glycol. You can find most properties on their website.
By the way, pure glycol does not make a very good heat transfer fluid because:
1. Vicsosity is high
2. Thermal Conductivity is low
3. Specific heat is low
Glycols work much better when mixed with water.

-40ÂșC is pretty low for PG; its viscosity is pretty mushy at that temperature.

RE: Propylene Glycol
I'm reviewing the tables right now and see what you mean, now that I have the info.[re: mixtures]
This is just what I needed.
Thank's
