Propylene Glycol

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

Steve,

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.

Thank you very much!
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

RE: Propylene Glycol

Whatever corrosive properties of PG there are, they pale in comparison to stomach acid, so that's not necessarily an indicator for not having inhibtors.
