Product Description

Eastman Spectar copolyester (PETG) extrudes into plastic sheet that is sparkling clear, tough, chemically resistant, odor-free, versatile, easy to work with and affordable. Its toughness allows fabricators to use thinner-gauge sheet than with other common materials, resulting in lower material costs. Yet 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, flame-polishing 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.

Sheet made from Eastman Spectar copolyester (PETG) is available from plastic sheet distributors throughout North America, Canada, Europe, Asia, and Latin America.
