Sure, but you probably want to see the absorption curves on their product
and compare them with the ones on the data sheet for 703 first. If the
curves look good, buy it.

Scott has the right answer. Density is only one factor, and the only way to
know for sure if a proposed product will work as an absorber is to see the
official lab data.
