low modulus?

low modulus?

low modulus?

(OP)
I'm looking at thermal material and it advertises a 'low modulus'.  I read that the modulud of elasticity is the amout of force required to stretch a material, but in this case I think it's the amount of force to compress a material, because the more it is compressed, ie the thinner it is, the more thermally conductive it is.  Is this the modulus to stretch something the same as for compression?

RE: low modulus?

If you are looking at polymeric materials, then the elastic moduli may be different in tension and compression.  For stiffer solids like metals and ceramics, the elastic modulus is unchanged in tension and compression.

Yes, in this case I think your reasoning is correct.
