Blister packaging machine PETG overview

Polyethylene terephthalate-1,4-cyclohexanedimethanol is abbreviated as PETG. In short, it is a transparent plastic and an amorphous copolyester. The commonly used copolymerization unit of PETG is 1. 4-Cyclohexanedimethanol ester (CHDM). It is the product of polycondensation by transesterification of three monomers, terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM). Compared with PET, it has 4 more -The copolymerization unit of cyclohexanedimethanol has more ethylene glycol copolymerization units than the PC plastic raw material PCT. Therefore, the performance of PETG is very different from that of PET and PCT. The technology is relatively mature.
