Hard Squishy Material
Hard Squishy Material
(OP)
Looking for an "elastic" resin that is rigid. This material must be "hard" but compressable. After compression, this material must return to it's original shape. Injection molding grade. EtO sterilizable (3x). Radiopaque. Biocompatable.
Durometer > 80 Shore D.
TPE ?
TPU ?
TPV ?

Check-out Santoprene by Advanced Elastomers
I believe that you will find most of the properties you seek within the material.

It's your design and the type of compression set ("return to the original shape") that you experience or find acceptable, will be up to (you) the part designer.
Good Luck!

RE: Hard Squishy Material
I think Advanced Elastomers have an exclusive on highly vulcanised TPVs (over 95% cross linked) due to patent protection, so they might be the only source.
Bayer and BASF could both supply info on PU, and Dupont and DSM could supply info on TPE.
I have no info on the EtO sterilizable (3x). Radiopaque. Biocompatable of any of these. You might need to get onto their technical departments to get this info. I expect most salesman will just give you a blank stare and platitudes.
You can enquire about the shore hardness from any salesman for these products or via the manufacturers websites as easily as I can. Your probably getting paid to do it. I'm not, so over to you.

RE: Hard Squishy Material
I have sampled high Shore A TPE,TPU, and TPV. The customer would like something more rigid. My next step is to jump into the mid to high Shore D materials. I have only found this in a medical grade PSU. What is the breaking point between rigid and elastic ?
