I am looking for a way to permanently color a finished product made from low density polyethylene. I am working with 1.25" thick sheets of LDPE, sort of a milling process, and I can only find it in white.
Is there a dye or some coloring process I can use? I assume it is tough (even if possible) as my attempts to use "indelible" markers have ultimately proved fruitless. I'd like to be able to put the pieces in a small tub of the color and then fish them out - like coloring Easter eggs.
(If there is a different newsgroup where I might find an answer to this question, suggestions welcome on that, as well.)
TIA. -- Igor
