PETG (the full English name of poly (ethylene tethalate co-1, 4- cylohexylene dimethylene phthalate) is a transparent amorphous polyester, and the common * * * monomer of petg is1,4-cyclohexanedimethanol. It is the product of polycondensation of terephthalic acid (PTA), ethylene glycol (EG) and 1, 4- cyclohexanedimethanol (CHDM) by transesterification. More 1, 4- cyclohexanedimethanol * * monomer than PET and more ethylene glycol * * * monomer than PCT. Therefore, the performance of PETG.
PETG board has outstanding toughness and high impact strength, its impact strength is 3~ 10 times that of modified polyacrylate, and it has wide processing range, high mechanical strength and good flexibility. Compared with PVC, it has the advantages of high transparency, good luster, easy printing and environmental protection.
