Polypropylene and aviation oil
Polypropylene and aviation oil
(OP)
I just want to know if some polyprolylene beaker will not dissolve if I pour into it Mobil Jet oil II at ambient temperature.
I have oil specs but does not say anything about polypropylene, just some rubbers and silicone appear.
for oil specs:

I'd appreciate any help.
Saludos/Regards

RE: Polypropylene and aviation oil
You got my attention because that's exactly what I wanted to use the beaker for, to measure volume...Oil will not stay in the beaker for a long time just the measure and that's it, but it will be several times: around every week or so, do yo think the beaker will swell significantly?
If that's the case, What kind of beaker do you recommend?
thanks in advanced.

PS:we wash the beaker after use.

I don't have any hard data available to me now, but the suppliers of the polypropylene moulding compounds should be able to supply actual measured data.
You could calibrate your beaker once a week or so by comparing to a glass beaker, or by weighing the indicated volume. You might need to test the SG with a hydrometer, to correct the expected to variations in the Jet Oil 2. I am not familiar with the actual spec of Jet Oil, but I am presuming it is mainly allephthatic (sorry, I have a brain fade and forget how to spell it, and it's not in my spell checker) hydrocarbons with some aromatics as well.
Alternatives are metals like stainless steel or aluminium if high levels of accuracy are not required, or glass if accuracy is required, but durability is not so important
