Product TextsApplication/Uses It can be extruded into sheets as thick as 12 mm (1/2 in.). It extrudes at a low temperature and will not crystallize or develop a crystalline haze. Cleaning solutions will not turn Eastman Spectar copolyester white. It is easy to fabricate, allowing greater design freedom. It can be laser cut, routed, welded, drilled, die-punched, bent hot or cold, or joined by screws, rivets, or bolts. It can also be cut on conventional table, band, or radial-arm saws with blades commonly used for plastic. Spectar copolyester can be vacuum formed at lower temperatures than other plastics without predrying the sheet. Eastman Spectar copolyester can be finished easily. Its edges can be polished by using commercial edge-finishing equipment, sanding, solvents, flamepolishing or buffing. It forms clear, strong bonds with commercially available cements and solvents. It accepts screen-printing, painting, and hot-stamping easily. Surface scratches or scuff marks can be removed using a common heat gun.
