PETG (Poly Ethylene terephthalate modified glycol)

PETG is a thermoplastic derived from modifying the commonly known PET homopolymer through a process called polymerization, resulting in a copolyester or PETG. This modification aims to enhance PET properties to cater to a broader range of applications. While PET originally consists of two monomers, Terephthalic acid (TPA) and Ethylene glycol (EG), PETG incorporates another glycol monomer, 1,4-cyclohexanedimethanol (CHDM). This addition disrupts the crystalline structure, resulting in clearer products, and reduces production temperatures. CHDM also imparts beneficial properties such as improved mechanical strength, increased toughness, chemical resistance, biocompatibility, antimicrobial properties, and enhanced solvent adhesion. Thanks to these properties, PETG finds applications in various industries.
