PETG Copolymer Chemistry
PETG is PET with cyclohexanedimethanol substituted for part of the ethylene glycol, which disrupts chain packing enough to suppress crystallization. The result is an amorphous, clear, tough polyester with a Tg around 80 C and a wide, forgiving melt-processing window.
This Concept is waiting for its first lesson!
