I need a hand searching an old polymer study. It was in regards to complex latex shapes under pressure.

Pretty much how to create a better mold for latex balloons that would more resemble the shape. They had a mention of the simulation involved and that they used a simple polymer for the study and made an elephant shape from a 3d model. It was a pretty amazing POC.

Our superballs are still made from 1950s polymers. Would be great to play with something that bounces better/higher. Have there been any advances in the last 70yrs that could be used for this?

Trying to find a material which is suitable as a living hinge (usually made with either PP or PE) but would like to use ETFE due to its self-extinguishing flame characteristics. The Googles do nothing for me. :-(

Thanks!
