Spectar UV Copolyester

Spectar UV Copolyester Eastman Chemical Company Copolyester Eastman Spectar UV 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 UV copolyester white. Eastman Spectar UV copolyester 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. Eastman Spectar UV copolyester can be vacuum-formed at lower temperatures than other plastics without predrying the sheet. Eastman Spectar UV 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.

PETG,PCTG,PCTA都属于是一种非结晶型共聚聚酯的高透明塑料.PETG塑料制成的板材通常比通用压克力坚韧15至20倍，比抗冲改性的压克力坚韧5至10倍。PETG具有玻璃一样的透明度和接近玻璃的密度，很好的光泽度，耐化学腐蚀，耐冲击可制成复杂外形容器的包装，具有高吸塑力，高光泽，低雾度，易于印刷，不易脱落
