Where can I find details of the physical properties of PUR foam used in composite structures. I am looking at a foam cored insulation for thermoplastic pipes. The inner core axial strain resulting from changes in fluid temprature will impose a stress on the foam core as the outer sheath is held stationary by soil.

I expect that the properties will vary depending upon the degree of foaming, mehod of foaming etc. Is there a text book, manufacturers guide etc to the design of composites specific to PUR foams. I would expect FEA analysis could be used but would need to be calibrated against physical tests.
