Least Brittle Polymer, Epoxy, Resin, Clay, or Putty?

Hello
I want to cast a polymer, epoxy, or resin. It must be crack-resistant when compressed. Prefer a clay or putty.
I tried JB SteelStik, and it cracked under compression.
Don’t need bonding.
Fancy expensive products are not an option.
Fyi, this is related to a youth engineering program i started, for at-risk teenagers.

etc..
Or, even better - soak old scrap nylon (old spatula, old kitchen plastic, etc) in water for a day, it will absorb wter enough to make it have a high dissipation factor at 25 GHz.
Place in melamine or glass bowl in microwave until pourable, and cast.
Let cool.

cut up washed hdpe poly milk or juice cartons, place pieces into a metal Teflon coated bowl.
Place in oven at 500F, remove and pour when melted.
