I need to create a few dozen opaque domes/hemispheres of various sizes from 80 cm to 120 cm. The shape is pretty basic, for example:
The domes have to be foldable into smaller pieces for easy transportation and storage. Think heavy duty rubber gloves but just dome shape.
I would like to know if there are elastic sheet materials available to create these domes that I could vacuum form similar to rigid materials such as ABS plastic.
I understand there might be rubber domes available for sale so I wouldn't waste time making my own. But I'm going to make slight changes to the perfect dome shape, so I need to make my own.
Possible candidates: TPE (thermoplastic elastomer), TPR (thermoplastic rubber), TPO (thermoplastic olefin), low density polypropylene, low density polyethylene, vinyl aka PVC, Polyurethane, EVA (Ethylene Vinyl Acetate). Some seller websites claim these can be thermoformed, but there is virtually no other source, video, etc. available online.
