I'm looking for a cost-effective silicone-rubber solution for a run of juggling spheres. The rubber should be as optically transparent as possible as I will be casting various objects inside of them.

It needs to have high tear/stretch/abrasion resistance characteristics as these will be frequently hitting the ground/juggler and I want the impact to be soft/painless while offering maximum lifespan and optical clarity.

Some examples include:

Many thanks in advance.
