Finding an elastic materials with ultra-low elastic modulus and low density

Finding an elastic materials with ultra-low elastic modulus and low density

Finding an elastic materials with ultra-low elastic modulus and low density

(OP)
Hello everyone,

I'm not sure if this is the right place to ask, my apologies if it's not.
I'm finding an elastic material that has very very very low elastic modulus, better with low density.
(preferred properties are shown in the picture)



The closest thing I could find is rubber, but all the elastic modulus I could find from the Internet are still too high.
Maybe this kind of special materials could be found from special material database, but I don't have access to them.
So I thought there might have a chance by asking you guys.
If you find anything, or any materials that strikes you, please inform me.
Thank you with all my heart.

Wish everyone be safe from COVID-19!

Please don't post the same question in multiple forums.

P.E. Metallurgy, consulting work welcomed

RE: Finding an elastic materials with ultra-low elastic modulus and low density

Foaming the rubber will reduce the modulus and density even further.

RE: Finding an elastic materials with ultra-low elastic modulus and low density

Air has very low elastic modulus and density.
