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

[NTUCE]

Hello everyone,

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!

Elastomer foams have low modulus and low density.
