Material properties for PP

Knowledge · November 23, 2020, 09:32

Hi

For my simulation in CFX I need to specify the wall material to be of polypropylene PP. I need to specify PP's thermal properties, but I can not find them on the internet. Do you know a online database for materials where I can find molar mass, density, specific heat capacity, thermal expansion etc. for the material PP?

Thanks

Maybe you should try a little harder:

Density: https://www.engineeringtoolbox.com/d...ls-d_1652.html
Cp: https://www.engineeringtoolbox.com/s...ity-d_391.html

And you don't need Molar mass, nor thermal expansion for CFD.
Btw, you'll never find a molar mass for PP since it depends on the polymerisation degree.
