Material Notes:
SKYGREEN PETG is an amorphous copolyester in which a certain amount of ethylene glycol is replaced with 1,4-cyclohexane dimethanol (CHDM), which prevent crystallization, leading to improved processability and clarity. Skygreen® PETG provides a material having outstanding toughness, clarity, color, chemical resistance, and resistance to stress whitening. It can readily be thermoformed for extrusion blow molded. It is superior to acrylic for toughness, and superior to polycarbonate for processability.Applications: Extrusion Sheet: architecture protective cover, display signs, industrial products. Extrusion Film: blister packaging, food packaging containers, electrical & electronic packaging, pharmaceutical & medical packaging. Injection Molding: toys, refrigerator parts, electric & electronic parts, smart cards, pen caps, medical devices and tools. Extrusion Blow Molding: bottles for cosmetics, soaps, shampoos, detergents, etc.Information provided by SK Chemicals.
