hello im working in a toy project that requires an injection molded polymer. It is for a joint that will connect wooden dowels to each other, These joints need to be stiff enough to keep the dowels in place and yet plastic enough that they can be moved around when placed in the joint. Im researching synthetic elastomers, acrylic elastomers. Ideally these parts would be injection molded or done with elastomeric casting
The 4’ x 8’ dimension isn’t too difficult to obtain, it’s the 2’ [thick] dimension that’s tough. Called a “bun” they used to be readily available. Not so much anymore.
That said, thinner sheets are cut from buns … so it’s just a matter of finding a source.
