Would this be good material for basstrapping.

The only way to know for sure is to ask the manufacturer if they have acoustic data, and compare that to known-good absorbing material.

Off the top of my head, I'd say no. It appears to be a rubber based carpet pad type of material which is no good for being absorbant of waves in the air. The only way to know for sure is to do as Ethan said.

Thanks for the advice.

It's difficult to get the exact absorbtion data per frequency for this material but I did a quick check in my room by just stacking multiple pieces up against the back wall and listened to the low freq response throughout the room with my Genelec 8050's at a loud volume. ( these are used as midfield monitors so an even room response is important; bigger sweetspot )
It turns out the room sounds pretty tight and even allready; it's not because of that material I think but because of the corner traps and I think the room dimensions help a lot too.

It can be tighter in the low end though! I will pick up some thick rigid fiberglass by knauff for the back wall instead.

Cheers,

Good choice. No need to spend hours building away to find out it did not work.
