Vinyl film can either be rigid or flexible. Rigid film is available either as calendered or planished.
Calendering is a manufacturing process by which sheets are produced in .005 - .040” thicknesses, and in a full range of colors. Calendered sheet is more brittle than planished and less expensive, yet it can be used in the place of the latter if further laminating and processing is required.
Planished sheet is calendered sheet that has been laminated using plates to give the finished sheet a polished or matte surface finish. It comes in a full range of colors with standard thicknesses of .010” to .125” and in special order thicknesses. It is also available in transparent, translucent, and opaque.
Rigid vinyl films are characterized by clarity, excellent chemical resistance and electrical properties, easy fabrication, good dimensional stability and flexural strength, and low moisture absorbtion. They are also self-extinguishing and have a forming temperature of 280° to 300° F. |
