Processing of Lumirror®
Like common plastic films, Lumirror® is easily converted through dyeing,
coloring, printing, coating, lamination,
vacuum evaporation, matt processing (etching), molding, slitting processes,etc.
As a result of its excellent
dimensional stability, thermal resistance, and chemical resistance, however,
Lumirror® can withstand more severe
processing conditions that would be impossible for other films to endure.
Note : These
values are typical data for this product under specific test conditions and not
intended for use as limiting specifications.
