PCTG, a transparent plastic, is an amorphous copolyester. The commonly used comonomer in PCTG is 1,4- cyclohexane two methanol (CHDM), which is called polyethylene terephthalate -1,4-, cyclohexane two methanol ester. It is composed of terephthalic acid (PTA), ethylene glycol (EG) and 1,4- two (CHDM) methanol cyclohexane three by transesterification polycondensation monomer product, and more PET 1,4- two methanol cyclohexane monomers, and more than PCT of ethylene glycol comonomer, therefore, the performance of PCTG and PET PCT, not the same. PCTG is a kind of non crystalline copolyester. With the increase of CHDM in the copolymer, the melting point decreases, the glass temperature increases, the crystallinity decreases, and finally the amorphous polymer is formed. PCTG is a high transparent copolyester plastic raw material. It has high transparency, good toughness and impact strength, excellent low temperature toughness, high tearing resistance and good processability, excellent chemical resistance. Can take the traditional extrusion, injection molding, blow molding and Blister molding methods for processing. Widely used in high performance sheet, shrink film, bottle and profile market; can be used in the production of toys, household utensils and medical supplies; through the United States FDA standards on food contact, can be used in food, medicine, cosmetics, packaging and other fields.
