I do not think there are still 100% pure organic rubbers. More on mix if natural and synthetic i believe.

This is going to take a lot of work. Is there a specific purpose?

I would rather see a complete list of objective topsheet + sponge hardness, Low, mid, high-impact bounce height, and friction coefficient. That would be a much more useful resource.

Do you have a reason for wanting this? Does the reason have to do with performance?

Camera lenses have MTF curves, wonder why rubber manufacturers can't publish response charts?
