I want to know whether any light foam is superior to PMI ( Rohacell) in thermomechanical properties ?

What properties do you look for?

To my experience Rohacell is a very good stuff with respect to weight, stiffness, thermal isolation and thermal range where it is stable.

Styro-foam hasn't got that stiffness.

But please look alternatively at PU based industrial foams such as

PUR RG30 to RG220 and PUREN 145

or 'google' for 'ZOTEK foams'.

I do not present you a link because I end up at internet pages with german language, sorry.

I have had an experimental look at them with respect to x-ray properites but not on thermomechanical ones. At a first glance hey have got stiffness comparable Rohacell; but please have a look at the data sheets for real quatitatative numbers.
