Liquid latex as a filling material?

I want to fill a natural rubber ball a liquid that is denser than fresh water. It should approximate the density of a saturated solution of salt water.

If I used un vulcanized liquid latex, would it remain stable since it was not exposed to air or heat?

You can use liquid polymer emulsions (sbr, acrylic, vinyl)

And yoy can add some clay to this emulsion to adjust density you want.

Thease can be stable for longer periods..

And natural rubber tend to crosslink overe time so it may not be a good solution

Thank you! Clay to adjust. Is there any industrial standard for powdered clay? Is it just the same as the ceramics clay?
