Default Thermal Characteristics of Mineral Oil

can anyone point me to a link to a site that lays out all the properties of common mineral oil? I have spent countless hours searching and stumped my bio engineering friend with this one.

Thanks.

Here is a site that deals with the properties of mineral Oils in Machine lubrication. Not sure if that is what you wanted, but it should give you a good starting point on "common" mineral oil.

Thanks for the link...... That is the only one I had already found that was some what useful.

I am specifically interested in mineral oils capacity of heat and rate of heat transfer.

Thanks again.

A quick Google for {thermal Conductivity "mineral oil "} found many sites with the info you?re looking for. Don?t type in the brackets, but do use the quotes.

Your results will vary greatly depending on the type of mineral oil you're interested in. Let me know if you have something more specific and I can probably throw some numbers your way. I used to test mineral oil-based lubes for the USAF, so I'm sure I have some numbers floating around somewhere.

Yes it yeilds lots of results, and not to be rude but you obviously did not click on any of the results as none of them really have anything to do with the answer I am looking for, I already did that search and many variations of it.

I am looking at standard off the shelf mineral oil, that which you would find in baby oil.

Thanks again fellows.

See the following text from this site: http://www.herguth.com/technical/PHYSICAL.HTM

THERMAL CONDUCTIVITY
Thermal conductivity is the rate of transfer of heat for a given temperature gradient through a material. The rate of transfer of heat from a hot spot to a cooler area in a bearing is a factor in controlling overheating. Therefore, an oil with a high thermal conductivity would be expected to lower the temperature of a bearing. Thermal conductivity of a lubricating oil is used in equations to calculate heat transfer in bearings. The unit of thermal conductivity is heat over a distance per degree of temperature. Most mineral oils have approximately the same thermal conductivity of near 0.1 W m-1 degree C-1. (For reference, the thermal conductivity of water and ethylene glycol are about 3 times higher than oils).

Thermal conductivity is measured using ASTM D 2717. This method consists of a test vessel containing oil and a platinum resistance thermocouple. Thermal conductivity is determined by measuring the temperature gradient produced across the liquid sample by a known amount of heat introduced into the cell by an electrically heated platinum element. Thermal conductivity increases slightly with higher temperatures.
For different types of engineered thermal transfer mineral oils see the engineering data sheets:

XCELTHERM®550 is a highly-refined mineral oil that offers you up to three times the thermal stability of typical hot oils * at bulk fluid operating temperatures up to 550ºF. This translates into savings for your operations, as its longer fluid life works to reduce your overall fluid costs.
