Anyone have any ideas as to a particular type or brand-name of thermopolymer that would exhibit the qualities as noted above? I liked Demon3's example of the PVC/calcium carbonate example. Would this be attainable when vacuu-formed in addition to stress formed?
hmmm, the effect is exactly what I'm looking for, but I really need to cheaply thermoform the part AND get this stress whitening effect. What I need is an easily stressed thermoplastic.
Demon3, that is EXACTLY the type of contrast I'm looking for, albeit via the thermoform process. You certainly described what I needed better than I did. Cheaply is the key of course. Are there any brand-names that come to mind I should try to acquire samples of for testing?
Thank You
That's very interesting stuff Demon3, thanks a bunch for posting. The thermochromic pigmentation sounds like the right solution. I'll do some research via google and perhaps follow up with a message on how I made out.
We use large format UV screen printers at our shop now. Perhaps I'll get a...
Thank you for your reply! That's what I had feared and your suggestion was my follow up plan..that is, to thermo-form a clear applique and sandwich it to a colored base with the lettering on the base in white letters. Possibly via a silkscreened process for large runs, digital printer for small...
Gentlemen,
Can anyone tell me if a thermopolymer exists that will noticeably and cleanly change color when vacuum formed? Perhaps more information about what I'm trying to do is in order.
I need to take a piece of this dark colored thermopolymer (for example, black) and vacuum form it over a...
