CAST vs CALENDARED
Hey Fred, how about combining the three or four posts and placing them in a CAST vs CALENDARED section for future reference?
It was explained to me by a VP at the old Fasson (now Avery) ...
Calendared vinyl starts out as a dough and is either extruded through a thin slot with pressure or rolled into a sheet using steel rollers. Either way the molecular memory of the film is that of a lump and it will want to shrink back into a lump when exposed to heat or as it ages. All that stops it from doing so is the adhesive.
Cast vinyl is liquified and then sprayed like paint against a "casting sheet" where it dries or cures and is left with the molecular memory of the sheet it dried as. Therefore, it has no tendency to shrink as it ages.
Cast vinyl is inherently more expensive to produce but it is also inherently superior for long term outdoor vinyl lettering and graphics.
